Just got a Surface Go, mainly for this program. Drawing right on the screen on the go is awesome. Thing is, ProMotion is meant to be used with shortcuts. Some of those icons are too small to use a touch screen with, or the functions are hidden away behind some menu or hot key.
Id suggest a customizable tool bar we can put whatever we want on.
For now, until that can get implemented, at least put the Eraser tool on the tool bar please. And maybe an option to switch back to previous tool after using it?
