"Delete session" button in session manager window does not have confirmation dialog

The "Session manager" window (which pops up when you select File->Session manager) needs a some sort of "Are you sure? This action cannot be undone!" confirmation dialog, because it's all too easy to wrongly click the "Delete session" button and oops, all bookmarks (w/ notes included), breakpoints, watches, etc you've been working so hard to set up get lost with the click of one single button.
