Seems like many moons since I last used K-9 mail and quite excited to see development has picked up again - for my purposes, it’s almost perfect. Thanks for all the hard word put into this project.
At this point I have a humble layout request: It would be nice to have a few more options to customize the difference between read and unread mail. I like that it’s possible to change the background of read/unread mail in the mail list, but it seems like you’re stuck with grey, being able to customize that color would add a nice touch. (If I could, I’d probably highlight the UNread messages in a light blue and remove that highlighting for the messages I’ve read.) And if you go with the highlighted background, I think it would make sense to keep the bold titles for all mail (or at least have the option to do so). Thanks!
