+# Erez's experimental layout
+
+This is my personal layout which I use to test out ideas which may or may not make it onto the default layout we ship with. It's based off the default layout, with various tweaks.
+
+Changelog:
+
+## Nov 1, 2016:
+
+* Adds dedicated text zooming keys in inner corners
+
+## May 24, 2016:
+
+* Implements Leader key example
+  * Leader, W sends Alt-F4
+  * Leader, O sends Ctrl-shift-o (a shortcut I use in FrontApp) 
+
+## May 8, 2016:
+
+* Makes bottom-right key send minus/underscore when tapped, L1 temporary toggle when held
+* Tweaked the positions of the numbers on the symbol layer. Basically, 12345 are now directly under their number-row counterparts in layer 0. You can imagine pulling the number row down to the home row. And 67890 are directly under 12345 - so it's a matter of just adding 5 and going to the next row (1+5 = 6, 2+5 = 7 and so on).
+* Tweaks media/nav layer
+  * Removes mouse control, as I don't use it
+  * Makes left home row keys PgUp, Home, End, PgDn
+
+## Apr 29, 2016:
+
+* Tweaks the Hyper and Meh key to send brackets when tapped
+* Turns bottom-right key into a minus/underscore (easy to reach with the right pinky)
+
+## Apr 25, 2016:
+
+* Made it so that the right and left Shift keys send opening and closing parens ( ) when tapped
+
+## Feb 11, 2016:
+
+* Updated ASCII legend for thumb clusters
+* Made it so outer left-hand thumb key is L1 momentary toggle
+* Added % and @ to L1
+* Swapped positions for _ and - on L1
+
+## Feb 5, 2016:
+
+* A whole new design for the symbol layer. Specifically:
+  * Put the minus, underscore, and semicolon right in the homerow for the right hand
+  * Parens are in better places for me
+  * The arrow keys now send Ctrl-PgUp and Ctrl-PgDn, for switching browser tabs with the arrows when in symbol layer
+  * Tab (right-hand outer thumb key) now does double duty to toggle symbol layer when held down
+  * Backspace (left-hand outer thumb key) now just toggles symbol layer (I wasn't using it as a backspace)
+  
+
+## Jan 19, 2016:
+
+* Made J into dual-action key (Alt when held down), to make Alt-tab more ergonomic.
+* Made ' into dual-action key (Win/Cmd when held down).
