I have a bug report and a couple feature requests. The bug is simply that the status bar does not show in landscape mode. The commands work, of course, but there's no status bar.
As for features, I'd really like it if launchpad would send the key presses to the program straight after they've been pressed, and THEN showing it in the status bar. Currently, it shows the success message and then sends the key presses. With programs like MPlayer, this results in a delay between, say, pressing the pause key combo and it actually pausing, usually around 1-1.5 seconds.
Perhaps it'd be nice to be able to turn off the status bar altogether?
Also, being able to add messages to display in the status bar when key combos are pressed would be awesome. Like MPlayer, pressing Shift M N goes to the next song. It's be nice if the status bar said, "Success! - Next Song" or something like that.
