[undo & redo as buttons on toolbar or below the tools]

Hello! I have bought a license from Affinity Designer, I use the program a Surface Pro, and the compatibility of the pencil is quite good (it works very well with drawing tablets), I wanted to ask if you can add the two undo and redo buttons in the toolbar or below the tools, since I like to use my Surface Pro as a tablet and remove the keyboard, having these two buttons in the toolbar would help me a lot, and for the whole community with Windows 10 touch screen, also I see that in the toolbar given to the wonderful organization that it has, I think you could add some buttons to allow us to execute a keyboard shortcut like Shift, Space or Alt, Thank You so Much.
