Just started using Aquamail and will probably upgrade. BUT, for me a tablet email app should never touch the server messages. When viewing an individual message (see screenshot), there's no Hide button, but there is a Delete. Unfortunately, that destroys the message on the server, so that when on my PC using Thunderbird, I go to download messages to my hard drive, that message has vanished from the server. Wishing the option was instead "Never delete messages from server."
