I'm deciding how to handle deleting and editing messages in a web chat app. For now, I can think of a few things I need feedback on.
- Deleting/Editing should have a time limit - maybe like SE, 5 minutes. Enough time for the user to realize a mistake, not enough to abuse it. I'm already kind of set on this, but feedback is always welcome.
- Delete the message, or 'hide' it, but still have it stored in the database? This may be more of a 'popular' site issue, this is just a little project I'm working on.
- I already want to keep an edit history, but should it be publicly available (like in facebook)? Or visible just to the message owner?
- Should there be a undo button - how to display it?
If you have any other ideas what I should look out for, please tell. This is my first time designing something that needs natural user interaction. :)
