Maybe the centre command deserves a button next to the zoom buttons, because it is too important to be a bit hidden like it is now.
I'd like to see a "Go to" box in the toolbar. If you enter lat/lon, it goes there. If you enter a place name, it uses whatever is the default geocoder specified in Tools - Options to go there. Might even allow specifying a hierarchy of sources, so you could specify a .map file that contained a drawing with points, where the "go to" lookup matched the nearest name in some default field and went to the location of that point. If there wasn't a match, it could drop down to the next default geocoder. That would allow using the Go To box for applications involving, say, hundreds of numbered oil or gas wells. Enter the well number and it goes there. Enter a place name, and it goes there too. Or, enter a lat/lon and it goes there.
