Ever since Ubuntu moved back to Gnome from Unity, it's impossible to minimize the Thunderbird Lightning reminder window. It's really annoying, the window is always on top of Thunderbird and has to be constantly moved around to use the program.

Closing the window makes no sense as a) it tends to start syncing the events with reminders, which can show conflict prompts requiring even more work from the user and b) the window comes back very quickly. So, minimize makes the most sense.
