Problem: the Bone Groups as they are shown currently in the GE interface create visibility problems as shown in this image:
- Hard to read the text
- Hard to see the icons
- Moving bone group color to a small strip on the right side of the curve channel.
- Adding the color of the curve to the text, making it more easy to find
Same, but using a gradient instead
Sybren suggested this idea in T68972: Graph Editor: Curve channel colour so I tried to combined both of them to check how it looks. I think it makes the interface more clean and readable.
Also recreated with the light theme, to check if it generates problems.
