• It's a single feature. Please don't request multiple features in one issue.

Describe the feature you'd like

It would be fantastic to have the ability to see an edit history for comments, and posts. It would really increase the trust level of the comments, and posts that you see by giving you some guarantee that they are authentic, and genuine -- it's very easy to create a comment, gain replies, and then change the original comment so that the replies are then meaningless. I have personally encountered this exact issue many times on Reddit, for example.

The format that I would like to see would essentially be a copy of what Element currently does where you click the "(edited)" tag beside the message, and a prompt pops up showing something like the following:

(the red indicates parts removed, and green indicates parts added). In Lemmy, I wouldn't necessarily want to see a pop-up prompt, but perhaps even just a drop down for the message, where you can select an edit from a timestamp history list, and it shows what changed in the message.

This would most likely require backend changes to Lemmy. I have opened a feature request for that here.

As an aside, it would be very good as well if ActivityPub were to implement edit history federation. Currently, there are a couple posts about this, here, and here.

What if I need to edit a post to remove sensitive information that was accidentally posted?

Deleting the post is still an option.

this would be great, and even better if it could show an edit notice the comment\post you replied to said was edited after the reply so people can see what the original comment\post was

The posts are not truely deleted. For an example, in Jerboa, click reply on a deleted comment and you will be able to see the contents.

Also not sure if the deletion is propagated throughout different instances.
