1. Let me turn off the functionality of the "End" key. I never, EVER want to jump to the end measure, but it's right next to the Delete button and I miss sometimes.
2. If you insist on the End key jumping to the end of the score, at least jump to the last few measures where the end measure is on the right side of the screen.
3. Let me turn off the "feature" that starts playback from the beginning if I spacebar-click on a time signature or key signature instead of perfectly within a measure. It's really annoying. Then I have to scroll through and find my place again.
