I've read other questions about why is there a 5 minute cutoff for editing comments but I don't think they address my issue. I don't think there should be a time limit on when you can edit comments. I understand that it often takes things out of context when you edit comments but I would rather have it editable until someone responds then the comments above would be locked. Does this make sense or are there disadvantages of doing so?
It makes sense to me, but you can essentially do this already. Since you can always delete a comment, if yours is the last on a post, you can just copy it, hit delete, and then add a new comment and paste it then make the changes you want.
