Thank you for including "Minimize to tray"!
It works fine but the way it's implemented is a bit "unorthodox" imho. What about just making "View-->Minimize to Tray" tickable: If it's ticked and you minimize the window it will be sent to tray and otherwise it will just minimize to the taskbar. I think it's a bit inconvenient to select an item in the menu and then the whole window disappears (though it of course does what it's supposed to).
