      <description>by Axel Schorcht. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;Hi for all of you trying to get this plugin to work on a current version of moodle and marvinjs:&lt;br&gt;
1. Download the zip and extract&lt;br&gt;
2. to resolve the mixed content error (https-&amp;gt;http) replace in structure\lib.php line 57 &quot;http://&quot; with &quot;https://&quot;&lt;br&gt;
3. the name of the marvin scripts are hardcoded, so in order to make the newest version (1.0.0) work replace in the following documents  promise-0.1.1.min.js with promise-1.0.0.min.js&lt;br&gt;
structure\yui\build\moodle-atto_structure-button\moodle-atto_structure-button-debug.js - line 218&lt;br&gt;
structure\yui\build\moodle-atto_structure-button\moodle-atto_structure-button-min.js - line 1&lt;br&gt;
structure\yui\build\moodle-atto_structure-button\moodle-atto_structure-button.js - line 215&lt;br&gt;
structure\yui\src\button\js\button.js - line 216&lt;br&gt;
4. re-zip the files and install &lt;br&gt;
5. enjoy!&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by Ilse le Grange. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;Good day, our Chemistry department is desperate for this plugin, or something similar. We're on Moodle 3.5 and cannot run the current versions. Are there any plans for updates, or can anyone make suggestions for alternative plugins/software.&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by Mashaal AlGhamdi. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;The plugin works perfect! thank you.&lt;br&gt;
For the new downloaders, just make the structure then click insert. After than, click on insert image of the editor tallbar.&lt;br&gt;
It works&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>
