TransmogSetProgress

By default the progress bars on the wardrobe set buttons shows the numbers of pieces of the most completed variant, in one continues line.
TransmogSetProgress replaces these bars with multiple if there are more variations, each showing their own progress by lighter colored blocks.

Different variations are also shows in different colors, making them easier to distinguish.
Raid sets are always colored by: LFR (green), Normal (blue), Heroic (purple), and Mythic (orange).
Due to a lack of localized variables by Blizzard, other sets with multiple variations are simply colored using the same colors, in order of their appearance (first is green, second is blue, and so on).

A settings button on the top right, labeled TSP, allows you to hide the bars of completed variations, and if you want to align the remaining ones to the left.
