+/* Things I did not like about the default mapping 
+
+   - I find control too hard to get to.  I think I'll want it on a
+     left finger.  Gonna need to lose something to do that...
+   - Almost certainly, KC_LCTL should be on [2][1]
+   - having dash on [lower-j] is a bit nonintuitive, but may be OK
+   - I'll bet I should switch ESC/TAB
+   - I'm suspicious that I want to shift M(0) from [4][1] to [4][2],
+     and shift ESC off the first column so KC_LCTL and KC_LALT can
+     be on the first column.
+
+
+   - I'm keeping Colemak and Dvorak around for reference, and added
+     Workman just for fun.  They're useless to me, though.
