Pretty simple. Like a word document, you can undo or revert text while writing out tweets.
An example would be you have a post you're writing out.
You use the AI to change it.
After it changed you didn't like the structure or aesthetically you didn't like how it looked.
You hit the Undo/Revert button and it returns it to its previous state.
Should be able to to this while writing a Draft or writing under the Schedule tab
