"And why is this maniac putting everything into the browser that does not belong there? Is the reason putting there is just to have it there?"

Haha, relax a bit. If it wasn't a browser application i wouldn't have tried it at all (most people here would not have either). I see it more of a toy than a development environment - but the fact that it seems fully functional and in the browser is impressive to me.

Anyways, 99.99% anyone using VB6 today is doing it for nostalgic purposes, not to develop real useful code - and that's probably what the project had in mind. Just a fun project.

If you did want an accurate no-changes recreation of vb6 on the desktop, just download the original vb6.
