Theme Editor is an addon that makes theme customization fast and easy.
- Edit your UI theme colors by groups (every matching color) instead of one by one.
- Highlight the currently selected UI elements, for easier searching and discovery.
- Filter by color, so you can simply click on the UI element you want to change to edit it.
- Filter by name, in case you are looking for something specific.
Works on Blender 2.7 and 2.8.
