Sorry for the delay!
The first issue, double click sets a key, has been fixed. You can see the problem even before you double click:

The key buttons should not show as edited (orange) just be stopping playback. Keep an eye out for orange key buttons, if they ever show when you didn't make changes, that is a bug!
Next, auto key making text boxes lose their selection, fixed!
Next, not sure it is the same issue, but I fixed this: if nothing is selected, holding ctrl/cmd and clicking bones only selects the first one.
