We're developing key modules that enable the community and 3rd party keyboard developers to create alternate key layouts.

I would love more keyboard options! If I could have a laptop with a keyboard more like a standard tenkeyless, I would be over the moon. In the meantime, I'll have to see about hacking the standard keyboard somehow, although there's no fixing those arrow keys.

Wouldn't it be possible to have a side add-on similar to the numeric keypad but the width of the spacer or LED matrix to accomplish this? Maybe a revamped keypad that has home, end, page up, page down, and then a bunch of assignable macro keys would work well.

Yep, definitely possible!
