Enhance Suggestion - Subfolder Colorizing, Enabled Checkmarks for Sub- and Top Categories

[cxbignekoc]

I want to suggest a colorized, better visible subfolder enhancement.

Also a ckeckmark that shows if a collapsed subfolder is active or not. I always struggle to figure out if its really activated. Then i open the subfolders and scrolling around.

Not shown in this Picture is that the Header of a Top-Category could also show checkmarks - for every Subfolders - in a Row.

[ x ] [ ✓ ] [ x ] [ x ] <- the second one is activated

The checkbox on folders part is something extension devs can already do, they just need to use InputAccordion provided by the webui instead of the standard Gradio accordion (folder).
