Looks great, numpad on left seems to be a trend lately but for me it would take a lot of unlearning. Nav cluster is indeed theoretically redundant, but arrow key placement in a t-shape rather than cross feels more efficient, less finger movement.
Yeaah, if I ever get myself to actually put this layout into action numpad5 would probably end up working as a down arrow alongside numpad2, too used to that t-shape movement.
And I see you also removed the caps lock - honestly why is that still even a thing in mainstream keyboards? I feel like its only purpose is to make you type passwords incorrectly on accident.
Preach it. I hate that thing and it's like in the most reachable position to accidentally press.
