Revisions Update, 2/19
Following two consecutive days of office hours, we’ve reached a consensus on what the UI should be for comparing a single revision to the current version of a post:
Based on the above mockup from @karmatosed, @adamsilverstein is continuing development of the new revisions interface on ticket #23497.
Once we have an acceptable, working prototype, we’ll revisit how to present the interface for comparing two different revisions. @nacin suggested, and we generally agreed, that a single slider with two grabbers would likely be a workable approach, but we’ll discuss that further once the above interface is implemented.
No progress to report on the other tickets scoped for 3.6 as we’ve been focused on UI lately.

1st thought: the chunks appear w/o context. (I imagine it with a snippet of before and after.) You okay with that?

Agreed, context is important. Just where in the document the shown snippet is located can make a dig difference.

yes, for sure.
although the mockup doesn’t make it clear, you will actually see your full document content, showing what has been removed, added (and what stayed the same), so the context is shown.

The chunks appear without context because the mockup happens to show a full post rewrite

I follow the GIT (or others) DIFF as the mockup shows a ‘ + ‘ and a ‘ – ‘ signs, but I don’t think the end user will need them. Maybe the colours is enough and we can have a cleaner screen.
