This is my side-project for now as I have lots of things to do.
No WebGL (most of the time). Currently there's no proper boot screen and dock yet.
Not really, as it's focused for the desktop web for now.
It follows the rolling release model: no releases, just little updates (and yes, that means it can break at any time)
Maybe... If you really want a cloud data storing feature, let me know about it in the Dicussions section!
Nothing else... for now.
