Apologies for the time it's taken to start reviewing parts 2-4, but here's some feedback:

Issue 1

After dragging a hairpin out from a dynamic, I don't see the popup appear. I'm assuming it's supposed to in this PR based on the description?

Issue 2 (crash)

If a hairpin has a dynamic at either end but NOT both ends, and I click the dynamic and change it via the popup, it crashes.

1. Add a dynamic followed by a hairpin via any method (shortcut, popup, dragging, palettes - doesn't matter)
2. Click the dynamic
3. Click any dynamic in the popup
4. Crash

The automatic switching of hairpin direction looks good!
