I came here to post the same suggestion. Had the idea when reading this:
Show edit notification at bottom of posts
I think reading longer posts will be greatly improved with a combination of this feature request and the one linked above.
- A better notification for new edits when reading a long post - the
notification and reload button is present wherever on the post you
- Highlighting new text so we can see exactly what was added
Reading the edit history is not really a good means of reading a post IMO.
So, clicking the "new edit" button wherever you are on the post, with the new text being highlighted, you can quickly scroll up to see if there is anything new in what you previously read because it is highlighted.
If no new text in what you've already read, find where you left off and continue reading, the new edit text will simply be highlighted and in the text you've not yet read.
