All the activities can use fullscreen actually, it's in the base
class. In matchbox the effect is just that the toolbars goes away, but
if you runned them on a standard desktop they would actually be made

My feeling is that the right approach here is to let the window
manager deal with the window sizing, on the base of the available
hints. That ways both activities and applications can behave in an
optimal way, depending on the window manager they run in.

The simplest implementation of this approach is maximus, i.e. the
window manager maximize all normal windows. This should work well for
most existing applications. For the side cases you'd have either to
get additional hints in the freedesktop spec or to use heuristics like
those David described.

Does it make sense? Can you think of better approaches?
