Happy to see thunderbird is doing better and better recent years. I think it is now the time to add an option to allow it automatically startup in the background on system startup, which has been asked for several years. That is a really useful option, why not just implement it? I think there are 2 ways: 1. Just automatically startup in the background on system startup and receive messages 2. Register a service in the background to receive e-mails and pop up notifications, and in this case, we don't need to add this option The first solution may be easier to implement, but the second seems better? Anyway, thunderbird should have one of them BTW, add an option to minimalize when click on 'close' button. I know there's an extension for this, so why not just integrate it :-) Thanks!
