I was hoping to do this just the other day. Copilot upgraded and enabled agent mode by default (we didn’t even have it before), and when I asked a question it started making a bunch of bad updates to the code. I clicked the undo button, but it didn’t completely undo it and left the code in a bad state. I was hoping to see which lines it touched, but it didn’t seem like I could. I didn’t have a fresh commit before it did its thing, so that wasn’t helpful on its own.
