I just saw the screenshot of the early design of the new UI, looks like crap.
I even disliked the change from wXwidgets to Qt way back in the day, I have come around and like the Qt interface now, I don't expect that to happen with the new UI
media formats it already does, and it is expected to support nearly everything. but as far as a front-end for whatever tf they're planning--there are plugins and extensions already, it should be there. not in the base code.
