Sometimes we create very complex appearance stacks, and navigating the Appearance panel becomes rather hard (especially given the fact it tries to unfurl the items in it all the time — look at this bug report: http://illustrator.uservoice.com/forums/601447/suggestions/49257335)

So with a lot of fills and strokes and effects given we would like to assign colors to the rows, the same way the Actions panel allows (for its button mode).

Another similar requests would be an ability to rename them (http://illustrator.uservoice.com/forums/333657/suggestions/34309852) and to make folders (http://illustrator.uservoice.com/forums/333657/suggestions/49257353)
