[Suggestion] Selectable Tab Icons and Tab Grouping

This could be useful for people with a lot of tabs on one character. For example, I have a character who has 8 tabs, a reference sheet, aesthetic, wardrobe, art wish list, stat block, and then three tabs for the different universes he appears in. Selectable tab icons and tab grouping could make it easier to find the tabs on characters with a lot of tabs.
