I would like the "add edit" function to work in empty sections of the timeline. I use this feature in Avid daily and it's a huge time saver.
If there’s nothing in the timeline, what would you want the ‘add edit’ function to do?

In Avid we use it for a number of reasons.
Add edit to all tracks - shows a sync point
Add edit to single empty track - g to beats - then can drop clips to those edits (like a temporary marker)
Add edit to empty track ('filler' in avid speak) then you can trim with it, eg assymetrically.
In Avid filler acts as an adjustment layer -so add edits there mark the extents of where you want to apply an effect.
Another advantage of 'filler' versus 'null' is that audio dissolves can be 'centred on cut' at all times.
