Suggestion: Favorite or most recent colors in costume editor

[biostem]

I've suggested something like this before, but I thought I'd have another go at it:  Most characters, (at least that I've seen), seem to stick to between 2 and 4 colors across their costume designs.  It can be annoying to have to remember that the particular color you were using was 4 columns in and 7 rows down.  To that end, what if the last 4 or so colors we used could either be differently highlighted within the current color palette grid, or maybe another row could be added that consisted of the last few colors we selected?  I'd love to hear your thoughts & feedback!  Thanks!
