i would love that live 9 or 8.2 would have bezier curves for automation.
also when editing :
left mouse button : add and grab notes/autmation points
right mouse button: delete notes/autmation points
middle mouse button pan view.
and use a shortcut for the piano roll options, we use more asdding , deleting and grabbing notes than that menu.
this improves the workflow so much.
also a visual refernce in paino roll :

and some advanced midi tools in piano roll like :

* Piano Roll Arpeggiator
