Great! Looks quite extensive and deeply thought-out at first glance. Respect for the discipline required to ship something like this by yourself. Keep at it :) Iterate till you win.

On the home page, if you can have two panes, some code on the left with your framework and output on the right to quickly get a grasp perhaps? Good luck!
