I recently found the Theme manager plugin and started trying to port the Material theme plugin to be a managed theme. I used the Dark theme as an example and saw that it changes two things, the main UI theme and the code box theme (I think it borrows from an IntelliJ theme?).

The Material theme also changes two things, the main UI theme and the icons used through the website. This made me think it would be nice if the Theme Manager allowed for theme sub-types. I think this would have two main benefits:

• Would make it easier for a developer to add their own sub-theme, as they can focus on the specific area of the UI they want to change (say the coding window).
• Would allow users more customisation options, as they could pick and choose between different main UI theme, Icon theme, code window theme.

Sorry if this is planned/already raise (I looked but could find anything with covers it).
