Advanced Themes - mithra62/ee_debug_toolbar GitHub Wiki
In addition to the above, you can also create more advanced functionality and have full control over the presentation of your theme. You can override the main theme JavaScript, Graph, and images (as well as the CSS).
Be aware: if any of the below directories exist the Toolbar will assume you have the appropriate resources available.
- images
- css
- js
To start, you should really just copy/paste the "default" theme into it's own folder. This theme has all the resources used and the folder hierarchy will match perfectly if you do this. Name it whatever you like.
Start customizing away. You have 100% complete control over all the theme options. You can change all the theme JavsScript, the template graph, as well as all the icon graphics.
