Well done, but quirky – What Note Is This? Review

The design is very well-done, and the program is exactly what I was looking for in a note learning app. There are a few occasional bugs that can interfere with it's usability (one required a forced quit). It would be nice if the keyboard could be locked, rather than scrolling horizontally to show 3+ octaves. That would help those of us with fat finges.
