That Undo Button Ipad

Any chance of an update for keyboard? Like maybe relocate that UNDO button to the top of the keyboard away from the space bar? I have bumped that button so many times and it wasn’t just one time. I tend to bump it accidentally a lot (multiple times) when I’m typing fast and switching over to quotes, numbers or hyphens and things. I’ve lost big paragraphs I couldn’t get back no matter how many times I would hit the redo button top left corner. I really don’t understand why it’s even there when undo and redo is already an option on the top left out of the way where it should be. Wish apple would make more keyboard options so I can choose if I want the undo button. It really messes up my flow of smooth typing when I’m all a roll.
