Tried (as Dirk already merged it into master :-)

In general I like it, one aspect I do not like. I ended my session, 
restart the application, and your previous zoomlevel is gone. And as the 
default is zoomed out very far (I see the whole world), you always have 
to zoom in again.

So, 1) a sensible default zoomlevel (and sensible is the problem here) 
or 2) preserve over sessions.
