Just personal layout tweaks :) (#2557)

* More ergonomic mousekeys

* integrate some recent hardware changes by changing the Plover keymap

* use TX Bolt support instead of Plover toggles

* switching to steno is no longer as intrusive, so this can move back to BASE

 - Layer 2: Plover-oriented stenography layer.
 - Layer 3: Extended media/mouse layout.
 
-## Unusual features
-The Plover key (top right key on the left half) also sends my Plover
-‘toggle’ chord (SH-FT) when pressed, as well as toggling the steno
-layer, so you can toggle between steno and typing modes with a single
-keypress.
-
-If you want to use this feature, you'll need to add the
-`commands.json` dictionary to your Plover dictionaries, or define the
-toggle stroke (`PHROLG`) yourself.
+## Hardware notes
+The default Ergodox EZ keycaps are delightfully staggered, which seems
+like it would make them terrible for steno, but in fact flipping the
+top row (`QWERTYUIOP`) and the middle thumb keys upside down brings
+them close enough together to give a rather pleasant steno experience,
+without interfering much with standard Dvorak typing.
