Please critique this control board

    I'm about to order this control board that I will mount to the belt cover of my knee mill. The two black buttons (bottom right) are looking for a feature. So please chime in with "you really need a button for ....."  whatever you think I have overlooked.The display (WIP) is capacitive touch-screen and will have several modes Manual, MDI, calculator, etc. with displayed values and additional mode appropriate buttons. 

Looks really really good.
