I’m a longtime Thunderbird user and don’t get all the changes they make. It’s a good functional client. I would rather want to see the parts not neccessary needed for an email client to able to disable, such as Calendar, Tasks and Chat. I use the RSS Reader, so that News REader functionality would be on for me. But can’t we disable all the other modules?
This and an first party integrated system tray icon showing number of unread messages would be extremely helpful (and maybe optional notifications). I’m baffled why these things are not builtin, but a Chat?
