In WordPress 4.5 the <a href="https://make.wordpress.org/core/2016/02/16/selective-refresh-in-the-customizer/" rel="nofollow ugc">selective refresh</a> framework was introduced in core. One of the key concepts in this framework is the “partial”, the region in a document which is selectively refreshed when a related setting is modified. This means that one or more settings are linked with a given element in the preview. When selective refresh was first was introduced it supported the ability for a user to “shift click” on a partial to jump to and focus on the related control in the pane. In WordPress 4.7 this was then enhanced with <a href="https://make.wordpress.org/core/2016/11/10/visible-edit-shortcuts-in-the-customizer-preview/" rel="nofollow ugc">visible edit shortcuts</a> so that users could click (touch even) on the icon to be able to reveal the control in the pane.
The Customize Inline Editing plugin builds on edit shortcuts by allowing the setting to be modified inline via direct manipulation in the preview without having focus removed and placed on the controls pane. This is particularly useful on mobile devices on small screens where a user cannot both see the controls and preview at the same time, as can be compared here:
<iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/w7WfSEtT8pc?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe>
Inline editing in this way is also helpful for accessibility since keyboard focus remains in the preview at the element being edited, as can be seen in this demonstration of inline editing on a desktop browser:
<iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/KesM3vo5WyE?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe>
This plugin provides one example implementation of inline editing this can be accomplished in the customizer. Version 0.1 of this plugin from 2014 was a precursor in some ways to selective refresh, specifically in regards to how CSS selectors are associated with customizer settings.
Themes can opt-in to support this plugin’s inline editing within the customizer by assigning the appropriate type to the registered partials:
<pre>
add_action( 'customize_register', function( $wp_customize ) {
 $opt_in_partials = array_filter( array(
 $wp_customize->selective_refresh->get_partial( 'blogname' ),
 $wp_customize->selective_refresh->get_partial( 'blogdescription' )
 ) );
 foreach ( $opt_in_partials as $partial ) {
 $partial->type = 'inline_editable';
 }
}, 100 );
</pre>
Click on the edit shortcut to begin editing the element, with keyboard focus then given to the editable element. If the value has a server-side rendered value (e.g. where PHP filters like <code>wptexturize</code> apply to improve typography), the raw value will be supplied when editing starts. Editing can be completed by clicking out of the editable element, tabbing out of the element (blurring it), or clicking the edit icon which then appears as a “done” checkmark icon. You may also shift-click on an element to edit it.
Currently only basic text fields can currently be edited; styling and any tags added to <code>contentEditable</code> areas will be stripped out. Eventually rich text formatting may be allowed, specifically for integrations with the Text widget (via <a href="https://github.com/xwp/wp-js-widgets" rel="nofollow ugc">JS Widgets</a>) or post content (via <a href="https://github.com/xwp/wp-customize-posts" rel="nofollow ugc">Customize Posts</a>).
The <a href="https://make.wordpress.org/core/2016/02/16/selective-refresh-in-the-customizer/" rel="nofollow ugc">selective refresh</a> writeup from 4.5 concludes with a section on a possible future for it and inline editing:
<blockquote>
If we can eliminate full-page refreshes from being the norm for the Customizer, we can start to introduce controls inline with the preview. If the entire preview does not reload, then the inline controls won’t get destroyed by the refresh with each change. For example, consider a widget control floating immediately next to the widget in the sidebar it is editing. With selective refresh, it will then also be possible to eliminate the Customizer altogether. The Customizer could be available to anyone who is logged in, with the controls being bootstrapped on demand when a user wants to edit a given element. There would be no need to navigate way from a page on the frontend to enter a unique Customizer state: the Customizer would come to the user. Any controls not relevant to being inline could remain in the Customizer pane, but it could slide in only as needed instead of appearing by default. That is to say, selective refresh makes the Customizer a much better framework for implementing frontend editing.
</blockquote>

Customize Inline Editing

Makes the whole text editing process smooth. From refresh to postMessage to inline editing awesome transition. Keep up the good work :)

Here are the plugin features:
WordPress Updates
WordPress has a major release three times per year, each time with a risk of breaking the way your website works. This plugin removes most of the messages to update (button from dashboard, the admin footer link and admin notice), while adding more information about versions to the updates page. You will see which version you are running and which versions which are available to you and given a choice about your updates.
WordPress also automatically updates your website to the latest minor release. We like that, but these updates can cause issues as well. That’s why BusinessPress delays the updates for 5 days.
This plugin also allows you to prevent your client from installing new plugins (many of which could either cripple or slow their website) while allowing clients to safely take care of existing plugin updates themselves.
<h3>You can disable the following capabilities for other admin users</h3>
<ul>
<li>Activate and deactivate plugins and themes</li>
<li>Update plugins and themes</li>
<li>Update WordPress core</li>
<li>Install, Edit and delete plugns and themes</li>
</ul>
Unnecessary WordPress features
Plugin by default disables the generator tag, REST API and Emojis to keep your site secure and fast. However you can enable these features back on if you prefer, just like the XML-RPC or oEmbed.
Login Logo
You can set your login logo and wp-admin color.
Admin Notices
Plugin by default moves the admin notices into Dashboard -> Notices screen where you can dismiss each notice. More and more plugins show their notices (some more important, some less) so BusinessPress cleans that up to keep you focused.
Login Protection
Plugin also supports fail2ban, see install instructions.
Login Lockout makes sure any user account that gets repeated bad login attempts (even from different IP addresses) gets locked down to ensure the password does not get guessed. User then gets an “Failed login attempts detected” email letting him unlock the account and reminding him to use a strong password.
Tweaks
<ul>
<li>Enable Google style results – Gives you similar layout and keyword highlight.</li>
<li>Enable Link Manager – Legacy feature of WordPress, hidden since version 3.5.</li>
<li>Enhance wp-admin Dropdowns – Makes long, unwieldy select boxes much more user-friendly, including search functionality.</li>
<li>Login redirection – After you log in you will be redirected back to the page where you clicked wp-login.php link, unless there was a custom redirect_to parameter. Uses HTTP referer.</li>
<li>Set Featured Images Automatically – First image in the post becomes the featured image on save.</li>
<li>WordPress core hotfix – are you getting error like “Unable to create directory ../images/2019/11. Is its parent directory writable by the server?” Since October 2019 WordPress doesn’t support ../ in the upload path. So we translate that path to absolute path and check if it’s in the site webroot and then let it pass</li>
<li>Disables the “Password Changed” admin email notifications when a Subscriber level user changes email address</li>
<li>Alphabetically sorting the wp-admin -> Settings menu, making it much easier to find any settings screen!</li>
<li>Hide Password Protected Posts – Password protected posts won’t show up anywhere unless you have the direct link or your are the admin or editor.</li>
<li>WooCommerce Search Speed – Speed up the search by only searching the billing email address and not shipping nor billing address.</li>
<li>Yearly dropdowns for posts filtering – If the standard list of months in wp-admin -> Posts or WooCommerce Orders and Subscriptions is going to show more than 10 months, the years will show instead. Will show only “Last 12 months” by default.</li>
</ul>

BusinessPress

There are too many upgrades of WordPress (2 per year) and plugins. When it just works as expected, I am always worried if something will break my site. The pace is too much and too fast to follow. It is very stressful for a webdeveloper, especially when you manage several websites. This plugin removes the admin notifications, consequently, clients will not be tempted to click the update button and break something. It does this without sacrificing the automatic security WordPress updates.
We do the updates when we decide to do them. It removes a strong distraction (the number in the red badge is always encouraging to click on it) than can generate troubles.

As long as there is no standard way to separate security and bugfix updates that are always welcome, from upgrades that add new features (and may potentially break something), this plugin is doing a good job.

There are other tweaks regarding overall security and performance but I don't care about them since other plugins offer the same with more controls.

This plugin is an answer to a growing concern from webdeveloppers

BusinessPress lets you control the WordPress core updates and plugin installing/editing/upgrading to prevent issues with your business websites.
