Mac OS X - Closing Filters/Effects window brings playlist forward in fullscreen
When set to not play video in the Main window and watching the video in full screen, you can open the floating Filter or Audio Effects windows, but when you close them it brings the playlist over top the full screen video. It doesn't do this if the video was originally set to play in the Main window. My feeling is it should't bring the playlist forward for a smoother experience when adjusting settings during playback.
