I designed a lil fantasy keyboard on a plane. Two Tabs, bigger and simpler modifier keys. Bonus: A bit more symmetry.

(The original is in the second image for comparison.)

@mwichary it has a fatal flaw! the tilde key is not on the edge, but the edge location is what makes it easy to switch windows in a single app.
@sayrer Maybe the new Tab keys take that over!
@mwichary I see. I suspect you're more of a tippy tappy typer than I am, where your fingers hit the keys more vertically. I type with them kind of flat, and never look, so this keyboard might drive me insane. But I could see a mechanical keyboard like this.
@sayrer I would be curious how much the edge matters in practice!

@mwichary oh, yeah, I was wondering why I felt this way. It's because I use a MacBook Air and a Magic Keyboard, and I value how close the layouts are.

But on the Magic Keyboard, where I do most of the serious stuff, my left pinky hangs off the edge while I am mousing around with my right hand.

I may also be a strange case, since I use different hands for different things (not quite ambidextrous: I throw left-handed but bat right-handed, etc)
