For me, remembering the last GoTo request and presenting it in the dialog would be a signigicant help.
The brass ring would be to add a new submenu to 'GoTo': GoTo|WayPoint. Then a combo box could be populated with waypoints and the user could just choose the one they needed.
Maybe I'm mis-using TopoFusion, but what I find myself doing is slowly building up tilesets of various areas around where I live. Â
I then reference various tilesets to map out bike rides. Â Understood that there's really only one tileset in Maps0.dat....but conceptually, I think of different sets as they are clustered about various geographic points....hence the desire to remember 'GoTo' requests by name. Â Then the user could hop around their area at will - without having to recall and type sets of Lat/Long numbers.
