As already explained, I can't spend one or 2 hours per day to implement all your problems and suggestions. So please make a list, give priorities, and explain why something is high on your list.
Maybe I can suggest you something: take the French Xcas for Firefox file
https://www-fourier.ujf-grenoble.fr/~pa ... casfr.html, translate xcasfr.html to xcases.html in your own language, then prepare your tutorials with links copied from the Clone menu of your sessions. It's much easier to follow a tutorial like this, because you don't have to install anything, just click on the link.
