I started to make some variable color initials again recently, and even using fullscreen and the largest possible layer panel, finding the right layer can be quite a pain, especially with many masters.
A lot of this could be solved by giving masters (with layers) the possibility to collapse, for instance using a dropdown. I know it’s possible to view only the color layers of the selected master, but sometimes I would like to pick and choose.
Probably I’m alone in this, but I’d thought: Let’s throw it out here and see what you all think ;).
When I manually close the sublayers I have more control over which masters I’m focussing on, and which layers I want to show hide.
And an added bonus for static color (color palette) fonts: I can quickly swap between glyphs which use different colours and keep the color preview. When I do this with the master swap using the F hotkeys, and the colours in the masters differ, I’m automatically sent to the fallback glyph.
