Flag unread mail prominently in the inbox
I use the tags to mark mail which I have already reviewed, but they are hard to see at a glance (white background).
Defaulting tags to a more prominent color (orange?) would solve this, but it might also be nice to add a separate feature to mark mail as read/unread and filter unread tags to the top.
P.S. Thanks for adding this ideas section. I work in software, and I love being able to participate in the backlog discussion for my favorite apps. P.S. Tmail (as I call it) IS one of my favorite apps. It's really great to see this company progressing and iterating. Keep up the great work, all!!! :D Much love - Ryan
