Why nobody puts something on the sides of keyboard? Espetially, rotary encoders? IMO, it looks and feels more suitable than on top side, along with keys.
Also why nobody places shift keys next to spacebar? Despite this, some people prefer longer spacebar, like 7x? IMO, 4.5u is the most optimal length for spacebar, and thumbs is more convienment for handling shift modifiers, than pinkies. But why nobody make keyboards this way for regular, not split, keyboards?
