Make a message tagged with 'memo, todo, done' colored again. + custom colours and tags
I installed airmail 2.0.3 yesterday, and now I see my messages that I tagged with todo,memo,done are plain white, with a little coloured arrow in te corner. Not only did you swap the colours for memo and todo, but a little arrow is just not enough to highlight some messages. At least give us the choice how a highlighted message must look!
Also, give us the option to use custom tags, with a custom colour.

Proper colours are back in Airmail 2.1. A big "thank you" to Team Bloop for listening to customers!

+3: This was one of the most important features to me, please make the colored background again.

+1. The lack of background colouring on memo/todo/done (replaced by tiny corner markers) makes the feature quite less usable.
