Fixed radio tuner bug.
[MenuTunes.git] / MenuTunes.m
1 /*
2 Things to do:
3 ¥ Radio mode makes things act oddly
4 ¥ Make preferences window pretty
5 ¥ Hot Keys
6     - hot keys can't be set when NSBGOnly is on. The window is not key,
7       so the KeyBroadcaster does not pick up key combos
8     - going to need a different way of defining key combos
9 ¥ Optimize
10 ¥ Apple Events! Apple Events! Apple Events!
11 ¥ Upcoming songs menu items are disabled after launching iTunes and playing
