The base layer is a merge of what I liked with the default layout and the ordinary layout. The thumb cluster is more like the Kinesis advantage and the top row of the cluster is convient for use on the mac.
The symbol layer can be tap/toggled with the bottom right key and also toggled on the thumb clusters.
The bottom two vertical mods are set to F14 and F15 which is the default for changing screen brightness on the mac
The app layer is used to control media playback and also some application shortcuts (OS X Focused). It can be toggled on the left board in the top left corner (tilde/grave) or using your pinky on the right side of the board using either ; or /. There is one additional toggle on the right thumb cluster for quick access to play and mute key combos.
The control layer is meant to help easily navigate and select text. It can also be stacked ontop of the Symbol layer when needed.
The right arrow key and End key toggle the control layer on the left board. There is also a tap toggle for the layer in the same position on the right side of the board.
On the left board you have mouse control with left & right click in the location of the G and B keys. On the right board you have vim-style arrow keys using hjkl
The left thumb cluster moves shift and alt within easy reach while holding the toggle (end). So far I've found this convient to navigate and skip around text when using the hjkl arrow keys.
