VLC crashes quite often on my Mac OS X, and it's a little annoying having to reconstruct my last playlist over and over again. Therefore I'd love to see a "session saver" or something, which automatically reconstructs the last playlist.
I've tried it with saving the playlist and then loading it again, but unfortunately that doesn't really work out because it doesn't recognize added folders without double-clicking them again first. Also, my playlist changes quite frequently and therefore it's not much use having to make backups of the playlist like every day.
Update: A session saver could also be useful for other settings besides the playlist. I have two screens, and whenever VLC crashes I have to manually change the video output screen to screen 2 again.
