The first thing I changed in my custom layout was to get rid of the number row.

Having all the numbers as a toggleable numpad (but not really numpad because numpad is archaic and dumb) under the left hand has been so good. I'm never going back.

I use this layout:

    1 2 3
  0 4 5 6
    7 8 9

This is pretty much what the Kinesis advantage has out of the box, although 0 is moved to a thumb key. I like it with the non-staggered layout there but on a normal (laptop) keyboard it's not as good IMO.

Miryoku does the same thing but the orientation is flipped vertically with the 0 below the center column, which is how it’s done on a full sized keyboard as well.

Miryoku basically has the numpad, which I still think is dumb to be quite frank since the numpad was only made like this for archaic historical reasons.

Having the 0 on the thumb is quite a good choice though. As long as one doesn't have to move outside +-1 of the home row of keys (like one has to with numpad).
