Please have an undo button. Sometimes by mistake you delete a text or a picture. It will be much easy and convenient to undo the last action. Wix.com has that feature.
It looks like this was posted to our Vote on Features board previously, so I'm going to mark this as a duplicate and link to the earlier post. Feel free to add your kudos to that to show support for it!
Great idea! Please Weebly, add an undo button!
One thing that weebly does enable is if you press Ctrl and Z, it automatically works as an undo button.
