GUI for Subpicture filters on MacOS X
It would be nice to have a GUI to access the subpicture filters (logo, time, marquee, mosaic).
There should be a button in the extended controls panel (Video filters section) and an entry in the Video-menu to show this to-be-created panel. Perhaps it can also be re-used for the wizard, so certain settings can be applied to the MRL of a certain stream only. We should be able to use the same panel for that. One could add a button to the "Transcode 1"-page to open it as a sheet.
The RC-interface's code by markfm and dionoea can be used as a manual for the implementation.
