Hi, I've been subscribed to captions one year ago and I was frustrated that after I deleted a caption paragraph, that I couldn't undo it, but I had to START ALL OVER. After one year I subscribed back and I see major updates in AI features, but basic features like undo? Please add undo and redo button. It was the reason I unsubscribed one year ago and it could be reason for me to unsubscribe AGAIN. Thanks
