It can't not take time from polishing, right? So, like, at the very end of the list, maybe?

IMO, there are enough players out there and wrappers for them. Native has the media player, then there's mplayer with kmplayer and SiB, there's VLC on its way, plus a few players and wrappers in beta, plus some media centers.

Yours would probably look best, but it's not like there's a shortage, plus, personally I'd rather have a polished, finished app than a multifunction media center. I have like 4 of those. 3 of them are YouTube enabled. Plus another like 4 or so youtube interfaces. And then there's the 4 browsers that do youtube, like MicroB, Fennec, Opera (I think), IceWeasel (at some point, maybe).

I know I'm one of many, but, since I get a vote, I vote for focusing on audio. I doubt such a software will ever be "done". No player ever is. Popular players for PC update like once a week for the last 5-10 years. There's always something.
