When in the Edit 'window' you can only edit the currently selected sequence. To move to the previous, next or later sequences on that track is a little awkward. You have to go to the Compose 'window' and select the sequence and click Edit again to edit that specific sequence.
I would like to suggest a little enhancement idea I thought of.
Basically, I would like to see the entire Track that the sequence inhabits at the bottom of the Edit 'window'. This would be scrollable and would enhance the ability to edit each sequence on a track. Rather than go back and forth to Compose then Edit.
It would be sort of like the 'MiniMap' feature in a text editor. Displaying the full track so you could scroll to a specific part instantly.
Is this something worth considering?
