Automatically sort tags by colour

[LeonNamowitz]

Idea Overview Automatically order and group all existing tags in the "My tags" and "Add to tags" lists by their colour (background colour)

Is your feature request related to a problem? Please describe. I use the tags to filter things based on multiple categories like actors, directors, composers, etc. Each tag is coloured by the group it belongs to, e.g. actors are yellow, directors orange, and so on. The problem is any newly added tag appears at the bottom of the list, making it an unsorted mess to apply and find all the tags in each "category".

Additional context Exact RGB match for the background colour is entirely sufficient imo because you can just copy the exact colour if you want tags to group.
