+ - Blue+Arrows = PgUp/PgDn/Home/End, which is intuitive for me.
+
+- The number pad: I placed the ten-key number pad on the Blue layer.
+ However, this would do the wrong thing when Num Lock was not enabled.
+ Rather than attempt to manage the state of Num Lock, I arranged the normal number keys in a ten-key layout on the Blue layer instead.
+ If you explicitly want the keypad keys, they're in the same position on the Red+Blue layer.
+
+- Number-pad add, subtract, multiply, and divide are located on the same keys as alphanumeric plus, dash, asterisk, and slash, respectively.
+
+- The Function-keys are arranged to mimic the order of the ten-key pad.
+
+- Enter is now in a more qwerty-familiar location, and may be activated with one hand.
+ Numpad Enter is in the same position.
+
+- Rather than place Backspace opposite Space, I intentionally place it on a layer where it takes some effort to activate.
+ Backspace is one of the keys I most dislike on a QWERTY keyboard because it moves me away from homerow and I need to use it so often.
+ Rather than make it easier to strike, I want to discourage myself from using it by learning to type more accurately.
+
+- Why do I dislike [snake\_case](https://en.wikipedia.org/wiki/Snake_case) (`__variable_names_that_use_underscores_`)?
+ Maybe because it's hard to type all those underscores requiring the shift key?
+ Hypothesis: I'll be less annoyed by snake case by placing `_` at an unmodded position, right near the `space` key.

+## Changelog
+
+### Current
+
+- Experiment: no-modifier underscore on right shift key.
+- New combined numbers + keypad arrangement.
+ No more worrying about Num Lock key.
+- Move F-keys to left board to make room.
+ Calling them "the Numbers layer" and "the Functions layer" is now less accurate but the arrangement feels better.
+- Audio working!
+- Move Tab and Space to upper thumb row.
+ I discarded the high-profile acrylic case from my Mitosis.
+ With a low-profile case, it's easier to hit the upper row of thumb keys.
+- Discard all my `#defines` for "Meta", "Super", and "Hyper".
+ I can call them that without making the code confusing to others.
+- Move Backspace to Red+A. I shouldn't be using it much anyway.
+ This means Tab and Shift might as well be separate keys again.
+- Distribute paired symbols symmetrically across boards like `\<{([ ])}>/`.
+ Opening-symbols on the right hand was a failed experiment.
+- Change default back to target a 16Mhz/5v Pro Micro.
+ I damaged the 8Mhz Pro Micro I was using so now I'm back to using a 16mhz Pro Micro again.
+
+### 0.6.1
+
+- Place Tab on Shift without a modifier. We use it frequently for autocomplete.
+- Make QWERTY the default layout. So more people can try it out. My customized Workman is easily toggled-on.
+- Don't use redundant `#define` for `KC_TRNS`
+- Place Num Lock somewhere. Otherwise (if it gets turned off) we can't type any numbers!
+- Add some media keys
+
+### 0.5.155
+
+- Enable use with my 3.3v Pro Micro
+- Add a toggle-able QWERTY layer
+- Golf down the LED-setting code
+- Place `!` and `?` on `Shift`+`,` and `Shift`+`.`.
+- Distribute paired symbols symmetrically across boards like `\)}]> <[{(/`
+
+### 0.5.129
+
+- A modified Workman variant for Mitosis
+- Arrows in home position, modifier + Arrow = PgUp/PgDn/Home/End
+- Load all paired symbols onto angle-bracket keys.
