Here’s an example - from this forum - of a case where I wish we had the feature I’m suggesting:
I’d like to suggest that @Eneroth3 remove the word “either” in the last sentence. Rather than alert her through a PM (or through a post quoting her and suggesting a correction - as this post does as a byproduct of the point I’m making), I’d like to just be able to “edit” her post, make a single change deleting the word, then have it sent to her as a suggested edit. I’m 98% sure she would have no problem with my making the suggestion in that matter - and it would remain a private matter between her and me.
If she only had one suggestion, she would likely simply accept my suggestion and the edit would happen. Or, if she indeed had more than one suggestion in mind, she’d realize that she only gave one suggestion, rejects my edit, and goes back and adds her other suggestion(s).
