Option to deselect notes when selecting automation? (And other suggestions)

I find myself deleting notes quite often - because a note will stay selected until I click another note, or click outside the note. Sometimes I’ll be working for quite a while before noticing a missing note somewhere else in my project.

I think an easy solution is to let selecting a parameter point deselect all notes.

Somewhat related (maybe needs a new thread): I think there should be an option to attach parameter points to notes. So that when we slide a note, the parameters move with it.
In Reaper this is a toggled option: “Move envelope points with media items”

Last: I find it inconvenient and unexpected that the mouse scroll doesn’t work while the pointer is over a parameter panel.
