Since we're talking about playback features: When viewing a chart in landscape (horizontal) mode on iPod Touch, the little black box that displays the repeat times ("3/6" for example) almost always scrolls out of view and, particularly when there's an Intro section, it never comes back. It would be great if the box floated at the top of the screen or in some other way stayed visible for the entire play cycle.

Also, it would be VERY helpful if a song could stop on the chord directly over the "END" character, rather than on the chord at the beginning of the bar. I'm finding that I need to end with an odd-meter bar to accomplish most standard jazz tags.
