I'm sure this has been raised before, but after working with the Maya graph editor for a few days just now:
Are there any plans on implementing a graph view like Maya?
The selecting of keys / tangents and the Middle mouse drag combination (select with left drag, middle-drag anywhere on screen to move selected thing, possibly constrained by modifier keys) is just such a pleasure to use.
This needs the graph/tweening handles in the same view as the dope sheet, and I realise this is not trivial. I just like really good UX, and Maya has that part down (other than being super overwhelming in other instances...).
Losts of animation love,
