It would be nice if the presets on the Artist's Pop-up Palette automatically adjusted based on the number of brushes in the preset, without exceeding the max. For instance I have one large preset that I use and have set the MAX Favorite Presets at 20 to accommodate. However, most of the others are in the range of 5-6 or less. This leaves the available palette space underutilized.

For example:

We did that initially, but we got complaints from artists who found it interfered with their muscle-memory.

Interesting. That wouldn't have occurred to me. Maybe an option in settings then for those who would prefer not to have a lot of empty space...
