<h3>Features</h3>
<h4>Licencing</h4>
<p>The free version, run without licence key has everything enabled apart form CCSS (critical CSS) creation. On our website TocToc Internetmanagement (https://www.toctoc.ch/en/getindexloaded) we offer a free licence key valid for one site and one month – which allows to run a full version of the plugin before you decide if it’s worth around 30 CHF a year (for 3 websites).</p>

– <strong>Developer</strong>: enables CCSS on 12 sites for a year</p>
<p>Privacy information: The free version of IndexReloaded does not any connection to third party websites, like ours – toctoc.ch. The licenced version connects to our website toctoc.ch for licence validation, the connection is strictly restraint to this purpose and does not send data outside the scope of licence validation to toctoc.ch.</p>
<h4>IndexReloaded Backend</h4>
<p>The backend is divided in two menu items, the “Overview” and the “Settings”.</p>
<p>For correct basic operation of IndexReloaded it will be necessary to identify JavaScript which IndexReloaded should exclude for its operations like regrouping, compression and defered loading). In some cases also CSS must get excluded.<br />
We supply an experience-based database that helps to indentify recommended excludes and – if some are found – adds them to the IndexReloaded Excludes list for your site – based on theme, plugins and elements found in your pages.<br />
This experience-based database is distributed along every release of IndexReloaded and licenced users can download a fresh copy of the experience-based database from our site in the backend of Indexreloaded in Overview->Recommended excludes</p>
<h4>IndexReloaded Overview</h4>
<p>In “Overview” we first focus on the basic operation of the plugin and on the challenge we have to solve to make it work properly.<br />
After this we have 3 tabs where the overall state of the plugin is displayed. You see if it is active and see the licencing state.</p>
<p>In tab “CSS and JS files” you see information on the css and js files produced by indexreloaded. With the “Delete files”-button you can remove all files on disk and force IndexReloaded to recreate the files.<br />
Tab “Licence key” informs on the used licence and its validity.<br />
Tab “Exclude list”, shows the proposed excludes for your settings “CSS and JS processing” setting “Exclude list” and delivers informations for the reasons why the excludes are recommended. These information come from the experience-based database.</p>
<h4>The experience-based database</h4>
<p>As we are on release 1.1.1. and this is valid for all subsequent versions, the experience behind the experience-based database <em>must still grow</em>. It is important to us to get your feedback on excludes you find in your site and which are not part yet of our experience-based database. So please send us your finds, along with plugins or themes concerned, to our moderated e-mail address knowledgebase@toctoc.ch</p>
<h4>IndexReloaded Settings</h4>
<p>IndexReloaded organizes its settings into groups for general settings, settings related to CSS and JS processing, to Critical CSS, HTML-cleanup, preloading and monitoring.</p>
<h4>General settings</h4>
<p>Within General settings, you can add a licence-key and setup some basic behaviors of the plugin, like where to store css and js-files, days generated files stay on disk and more. With setting “Activation” you activate or desactivate the enire frontend processing of IndexReloaded.</p>
<h4>CSS and JS processing</h4>
<p>The first part of these settings concern what IndexReloaded processes regarding CSS and JavaScript. You can turn off everything, turn off CSS or JavaScript-processing individually.<br />
As the core setting, the “Exclude list” allows to identify JavaScript and CSS that must be left intact by IndexReloaded. It’s a core setting because here you can make all possible errors disappear by add correct identifiers.<br />
The identifiers in this comma-separated list can be for example the id of a script or part of a filename, for inline JavaScript even parts of the code may be used as identifier.<br />
Setting “Force new files” is handy when developing the “Excludes list”, alternatively one could delete all files in “Overview”.<br />
With “Production mode” all 3 URL-Parameters we can pass along the request form the frontend, will be disabled.<br />
With “Load last JS file asynchronous” one can either defer or not defer the JavaScript-files created by IndexReloaded.<br />
Even after he grouping of JS by IndexReloaded some JavaScript will remain in HTML. Setting “Defer remaining JS after processing” defers this JavaScript. This is important for the (final) elimination of renderblocking elements.<br />
You got a ‘jquery not found’-errormessage after enabling “Defer remaining JS after processing”? Setting “Do not defer Jquery” allows to exclude jquery from deferal.<br />
The “CSS compression” setting enables or disables minimizing CSS files. By reducing CSS size, the plugin significantly improves page load times.<br />
The “Minify JS” setting enables or disables optimizing website performance by reducing JavaScript file sizes. This feature uses a third-party JavaScript minification tool, run on your site. By enabling Minify JS you reduce JavaScript size, optimize script delivery and boost web page efficiency.<br />
Setting “Minify exclude list” allow to identify JS that must not be minified, if ever this would be needed.</p>
<h4>Critical CSS</h4>
<p>This feature of the IndexReloaded significantly improves page loading speed by focusing on critical aspects of optimization. Above-the-fold Critical CSS adds up to non-blocking JavaScripts to streamline the critical path for fast rendering of essential content. Setting “enable folding” will split the grouped CSS to inline critical CSS and to deferred (asynchronously lazy load) non-essential CSS for improved performance. In addition, if some CSS-part found in original HTML does not sort out any critical CSS, this CSS may be dropped with setting “Remove CSS from CSS below if it doesn’t sort out CCSS”.<br />
Critical CSS is based on the HTML as it is displayed on the client around 2 seconds after page load. With this the urge to specify “Tags to keep above the fold” (or classes or Ids to keep above the fold) is very rare.</p>
<h4>Preloading</h4>
<p>This setting within IndexReloaded focuses on optimizing website load times by proactively preloading critical resources. This feature allows to force preloads of essential assets, such as fonts, scripts, or CSS files that are required for the initial page rendering process. By fetching these key requests ahead of time, it significantly improves page speed.<br />
However as these settings apply to every page of the site use preloading prudently. Apart from font-preloads, a preload will only show up if the filename is present in the HTML of the page.</p>
<h4>HTML Cleanup</h4>
<p>The settings here allow to remove parts of the HTML which are often considered as useless. Note that setting “Remove HTML-comments and generator meta” leaves intact comments by ko.js.<br />
But most HTML clean up is done automatically. For fonts loaded over Google it uses the “swap” mode for web fonts to ensure that a fallback font is displayed immediately, preventing a flash of invisible text (FOIT). Additionally, it optimizes the loading of Google Fonts, ensuring that content remains visible during the font-loading process.<br />
Also it makes sure that all images have alt, width and height attributes.</p>
<h3>Uninstallation</h3>
<p>When you delete the plugin, it will automatically keep all settings. During this process, the directory containing optimized files will be removed and possible cache entries in the database will get deleted. Please note that uninstalling the plugin will not remove the settings of the plugin.</p>
