Several times, I've pressed ⌘Q when Session had focus and I thought another app had focus. Session dutifully quits when you do that, but it also loses the currently running session and all of its notes. Instead, one of these changes would avoid losing work: 1) make Session pop up a confirmation modal before quitting with ⌘Q, 2) Disable ⌘Q entirely forcing the user to quit with the menubar, or 3) make Session resume the session that was running when it was quit last if it was quit in the last few minutes.
