I use it for two things.  

First, as an enhanced slippymapchooser.  It lets me quickly find new
areas to edit without opening up the dialog and resizing it.

I also use it to browse around the map and find problems.  I used it to
clean up most of Oregon's motorway_links that aren't attached to
motorways, for instance.

I guess I could go check this code out as well.  It would be nice to
merge them.

I thought this was already a feature, but I'd be happy to go back and
revisit it.  To me, it doesn't make a lot of sense to do this.  How do
you use it that this is important?
