I'd actually remove the gaps (sort of how they did on MPC already) or make them smaller to have even wider buttons, but easier to visualize this way.

This achieves vs current mpc2:

-1.5 keys worth of width on number row
-2.25 keys worth of width on qwerty row
-2.25 keys ... on ASD row
-2.25 keys ... on ZXC row
-1.5 keys ... on space row

Without basically losing anything valuable.

Now imagine what basically (on average) 2 extra columns of width can do to current mpc2 buttons. The keyboard would be less off center (good for thumb typing) and have wider keys (making it touch typeable).

There's no reason for cramming a 100% layout into 7 inch form factors like they keep insisting, when even pocket 3-4 didn't do it. This only leads to BOTH poor touch AND thumb typing experience due to extreme off center layouts and being forced to use switches that aren't good for thumb typing (because they aren't making custom switches).

CTRL ALT next to one another for thumb mode. Can always have more fn keys (like PG up down on arrows etc.) but I got lazy.

A productivity focused device should have a functional keyboard in both modes, you can't expect someone to always hold their device in the hand. This layout achieves optimal typing experience for both thumb and touch, with minimal compromises.

What I wish the new MicroPC 2 keyboard looked like.
