OS X: Inconsistency with Show Previous and Next buttons
Under the menu View --> Show Previous and Next Buttons.
If you play video in a separate window, the playlist window has a short click on the RW/FF jump briefly as expected, but the video window still interprets a short click as a chapter jump and the extra buttons aren't added to the video window. The extra buttons should appear in both windows.
Playing video in the Main Window seems to be fine with the added buttons.
