The biggest limitation I'm experiencing with Beat Note currently is the limitation of only one-bar exercises on a worksheet. Support for multi-bar exercises, or 'phrasing' would be huge. 2 bar phrasing - a kick pattern that repeats over 2 bars. Or writing out a drum fill from a beat, where the full phrase may be 4 bars long. Being able to write exercises up to 8 bars would be ideal (or really any multiple - the layout wouldn't change, but each exercise and the labeling of them would just become multi-line - perhaps 4 bars per line - This could be accomplished dynamically). Perhaps the UI could support 4 bars per row, and if an exercise is 8 bars then it would just consume 2 lines, 16 would consume 4 lines, etc.. I can currently kind of work around this by using the sheet music mode and exporting pdf at 4 bars per line, then noting the exercise numbers manually after export... but then you dont get the playback features 'per exercise' and the time signature/staff markings aren't consistent on subsequent exercises, nor are the 'exercises' numbered since its a sheet music beat. One bar exercise is great for beginner lessons, notes, etc, but it becomes a limitation very quickly.
