Are there any plans to combine VE with an inline visual differ like Extension:WikEdDiff?
VE is awesome, WikEdDiff is awesome. The mix of both would be super-awesome ;-)
Topic on VisualEditor/Feedback
It's been thought about, but I'm not aware of any plans to do this (at least, not in the near future). I think it's on the "probably someday" list.
That should be added to Phabricator, even if with a low priority.
Done: phab:T105173.
