Do you have any plans to add message filters/rules? I get a a ridiculous amount of mail and find the ability to automatically colorize a message in the message list view based on its headers to be very helpful in not missing the important ones. For example in Thunderbird, I have rules that set the text color of a message in the list based on the to, cc, and subject headers. (Thunderbird uses bold/non-bold text to indicate unread status.)
I found the ProfiMail has similar functionality but I also find AquaMail generally superior!
Thank you for a great App.
