Minimized startup after entering the password possible? Rated 5 out of 5 stars

It would be nice if there was a function in startup master to start thunderbird minimized. I have quite a lot of accounts in thunderbird and it takes some time after entering the passwort until everything is loaded and ready. In the meantime i do something else, and its quite annoying when the thunderbird window pops finally up and then interrupts e.g. typing in another window.

This review is for a previous version of the add-on (1.6.3).
