These changes are awesome!
I don't know how much you want to pursue event features that are pretty specific to sleep scoring, but other features that would be helpful in that regard:
- Ability to optionally set it so that two events of the same type cannot be simultaneously assigned to the same page -- for example if you add an event "Stage 2" to a page that is already marked as "Stage 1", the 2nd event would overwrite the first, instead of both being present. But obviously, for many other applications you do need to have overlapping events, so this would have to be optional.
- Ability to skip directly to the next page that does not already have an event assigned -- for this type of scoring you have to go back and forth a lot, and it takes time to scroll back to exactly where you left off.
