GREAT improvement to Folder access in this most recent update ! It would be fantastic if when using the "Move" function - folders also allowed the open/collapse feature.

read messages now hard to see text on in dark theme. the new update is really difficult to use. unread were great in grey but now all read I grey and unread in black is more difficult. the suggestion is worse in that all the emails are black and hard to see which are read or unread. can't you just undo the change you made to fix a non existent issue or provide a version to revert to please. I would like to try the beta but that has the same problem so why??

Nice app, lacking some features. Missing a widget for individual inboxes. Can only set a unified one....

It's 'useable', depending on what that means to you. Actually, it's cumbersome, über-convoluted SHITE! DEAR DEVS; do NOT look at Thunderbird! Do NOT look at older versions of K-9; and certainly do NOT look at – in dev-order: Outlook Express, Netscape Navigator, or Outlook! DON'T look at 'The Bat!' for inspiration! On Desktop, KILL the Thunderbird Fiasco & study "Courier"; pre-Calypso! On Android expand on "Kaiten Mail" the pun on K-9+1 Mail! THOSE TWO ARE THE ONLY EMAIL CLIENTS EVER WORTH USING!

Update: 100% still holding back because interface is still not fixed. FIX THE HORRID INTERFACE. Held back my update because the new UI makeover is a huge step back. Devs, you need to roll everything back and start over. Sometimes the best programming day is the one where you get rid of a bunch of code. Toss it.

Works great and probably one of the most secure email apps available. Avoid gmail, outlook, O365 and anything you dont host on your own private servers. Block big tech.
