Thanks for pointing to T2639. It's true that T2639 and all the bugs listed as duplicates of it are essentially identifying the same workflow problem. That points to how important this issue is to fix.

If there's multiple edits, you show the edit responsible for the text you see. It's like "who wrote that" except it works in history view and shows the edit responsible. If there's an exception that doesn't work, please specify it. I'm a developer, this strikes me a dead simple to get done.

Sorry for the lack of precision. By "Hover mouse over edit location" I mean the location where changes are shown. That could be highlighted text in the case of addition of text (blue highlight) or removal of text (orange highlight), or a "+" paragraph in the case of adding a paragraph, or a "-" paragraph in the case of removing a paragraph. The idea is that when your mouse is over an edit, you should be able to see information about that edit.

Steps:

1. Click here on PC: https://en.wikipedia.org/w/index.php?title=Climate_change&action=history
2. Change radio button on the left to be the last edit on the page (50 edits ago)
3. Click Compare select versions
4. Look at first edit, see there is no information about the edit
5. Hover mouse over edit location

Yeah, I guess frustration seeped into the bug. That comes from spending a few hours of trying to fix articles to not look like trash in the app, then realizing it was impossible for a lot of them.
