I really like that! Can you draw a bounding box to zoom?
Yes, you can zoom around, although the map in the sidebar is a little small.
It brings up another issue which I've been thinking about for a while.
Sometimes you dont want to render the entire dataset - there
could be too much data to process (and the styles dont have
min/max scale hints). I've certainly dealt with systems with
upwards of 20,000,000 features in them.
Yes that could be a problem. We still have to implement obeying scalehints
in mapbuilder but it shouldn't be hard to do as long as the WMS also used
them.

Hrm. I'd be surprised if we implemented Scale hints very well, as we're
struggling with min/max scale stuff in the renderer now. In fact I
don't think we support it at all.
For it to work right we'd have to have the scale hints generated
automatically, since we can't expect users to add them all the time for
huge datasets.
This actually is a bit worrying, now that I think about it a bit more.
Having super large data sets loading up by default is probably not the
best. It's great for users just get started. I suppose we should have
an easy access 'off' button, or some such. Or maybe have new layers
just added as optional layers, but not turned on? Sending full getMap
requests at every web admin page load seems like not the best idea.
Also I think we should get rid of the cite stuff, just have it available
as a separate download, which is super easy to do with the new data dir
stuff. Maybe a nice admin boundaries of Africa, to take up the middle
section... I think I can get that pretty easy from geonetwork.
