A plugin that adds “Add”, “Save”, “Restore” and “Delete” buttons to the Widgets configuration page with the following 
functionality:
<ul>
<li>Add: Adds a new named widget layout and saves the current widget layout against the new layout name.</li>
<li>Save: Saves the current widget layout against the selected layout name.</li>
<li>Restore: Restores the previously saved widget layout. If the theme name shown next to the layout name in the 
drop-down matches the current theme, widgets will be restored to the sidebar they were located in when the layout was 
saved.</li>
<li>Delete: Deletes the selected widget layout – does not modify the current layout of the widgets.</li>
</ul>
Note that the behaviour has changed from version 1 – widget layouts are not automatically restored when themes are 
switched. Layout choice is now a manual step since it is possible to save multiple widget layouts for a given theme. 
Once a theme has been activated, use the “Layouts” drop-down to select a previously saved layout that matches the 
current theme.
The reset button has been removed as it was too easy to remove all widgets with one click.
<h4>Typical Usage</h4>
This plugin is useful for trying different widget layouts, making it easy to revert back to a previous layout if the 
current layout is not working. It can also be useful when switching between themes. Different themes will offer different 
sidebar areas, and often there is not a direct mapping from one theme’s sidebars to another. This plugin can be used 
to save a widget layout for each theme. When the themes are switched, the appropriate widget layout can then be restored 
saving the time it usually takes to drag each widget from an inactive sidebar into the correct sidebar.
A typical process would be as follows:
<ol>
<li>Type your own layout name into the text field, and click “Add” to add and save the current widget layout. This name 
is now available in the “Layouts” drop-down.</li>
<li>Rearrange the widgets, move them to different sidebars, or move them into the inactive widgets box.</li>
<li>Type a new layout name, and click “Add” to add a second widget layout.</li>
<li>Select the layout name you created in step 1 from the drop-down, and click “Restore”. Your widgets will be 
repositioned to match this layout.</li>
<li>Select your layout name from step 3, and click “Restore”. Your widgets will now be repositioned to match your 
second layout.</li>
</ol>

Widget Saver

Saves the current widget layout and allows the layout to be restored at a later date.

TrustedLogin

The easiest and safest way to restrict access to your WordPress site’s Dashboard and administrative menus. Remove Dashboard Access is a lightweight plugin that automatically redirects users who shouldn’t have access to the Dashboard to a custom URL of your choosing. Redirects can also be configured on a per-role/per-capability basis, allowing you to keep certain users out of the Dashboard, while retaining access for others.
<ul>
<li>Limit Dashboard access to user roles:
<ul>
<li>Admins only</li>
<li>Admins + editors</li>
<li>Admins, editors, and authors</li>
<li>or restrict by specific user capability</li>
</ul>
</li>
<li>Choose your own redirect URL</li>
<li>Optionally allow users to edit their profiles</li>
<li>Display a message on the login screen so users know why they’re being redirected</li>
<li>Allow specific admin pages through the redirect — paste a list of URLs your customers should still be able to reach (with wildcard support for grouping related pages)</li>
<li>Optionally extend the block to <code>admin-ajax.php</code> requests for stricter lockdown</li>
</ul>
Blocking access to the Dashboard is a great way to prevent clients from breaking their sites, prevent users from seeing things they shouldn’t, and to keep your site’s backend more secure.
Allow only users with roles or capabilities:
You can restrict Dashboard access to Admins only, Editors or above, Authors or above, or by selecting a specific user capability.
Grant access to user profiles:
Optionally allow all users the ability to edit their profiles in the Dashboard. Users lacking the chosen capability won’t be able to access any other sections of the Dashboard.
Show a custom login message:
<ul>
<li>Supply a message to display on the login screen. Leaving this blank disables the message.</li>
</ul>
Allow specific admin pages through the redirect:
Sometimes you want to lock down the Dashboard but still let your customers reach one or two specific admin pages — a payment confirmation, a <a href="https://www.trustedlogin.com/" rel="nofollow ugc">TrustedLogin</a> secret-share screen, a custom report. Paste those URLs into the Allowed URLs box (one per line, relative or absolute), and matching requests will skip the redirect.
Use <code>*</code> as a wildcard inside a query value to match a whole group of pages at once. For example, <code>?page=tl-*</code> allows <code>tl-secrets</code>, <code>tl-config</code>, and any other page whose slug starts with <code>tl-</code>.
Optionally block AJAX requests too:
By default this plugin doesn’t touch requests to <code>admin-ajax.php</code> — most WordPress sites rely on those for legitimate frontend AJAX. If you’d rather the dashboard restriction apply there as well, turn on the “Also block AJAX” checkbox in the Advanced section of the settings page.
