Would like to see keyword colors in outliner so I can do this:
Have you tried adding Keywords as a column to your outliner? It won’t present keywords as coloured boxes like that, but the keyword names will be colour coded which in my experience works well for quick recognition (and maybe better if you have lots of keywords).
Do you mean the underline color beneath the word? Or is there a way to make the keyword itself have color?
Just the underscore. Colouring the whole text would leave a good number of colour options illegible.
