Displays:

<li>Thumbnails</li>
<li>The Loop (content)</li>
<li>Footer</li>
<li>Included template parts</li>
<li>Highlight script, link and style elements</li>
</ul>
To remove all registered scripts and styles add <code>?remove-scripts</code> to the URL. All these scripts and styles will be listed at the bottom of the footer as HTML comment. This way it is possible to detect non-WordPress script printing.
If you are not an administrators add <code>?view-source</code> to the URL to activate Frontend Debugger.
Notice: This plugin uses regular expressions and <code>eval()</code> to get the current template apart.
TODO: sidebar, search-form.
The mini control panel contains:
<ul>
<li>Header, Thumbnails, The Loop, Footer, Included files anchors</li>
<li>Toogle button for line numbers</li>
<li>Toggle button for line wrapping</li>
<li>Toggle button for showing line ends</li>
<li>Button for script and style highlighting</li>
</ul>
From the second click on the <code>Highlight</code> button loops through (scrolls to) all scripts and styles.
The control panel’s state is kept in your browser’s <a href="https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage" rel="nofollow ugc">localStorage</a>.
Development of this plugin goes on on <a href="https://github.com/szepeviktor/frontend-debugger" rel="nofollow ugc">GitHub</a>. Please contribute by sending PR-s implementing my TODO-s.
