What ideas?
Mainly, the program is a little clumsy. To edit/create maps, you have to select 'edit maps', then select your map, edit it.....close that page, close the map list, then check whether your settings suck.....
One...at least I....would expect that clicking on the map being shown would cause a pop-up of that map to be edited. Actually, I would make it even simpler: the main window size can be selected (perhaps as a percentage of some reference size), and editing is possible right from that window, so you can simply look over an inch or so to see whether your settings suck.
Further, perhaps other settings (restrictor, etc) could be displayed with the map - but at the very least could be accessible by right-click on the map, or/and from the FILE menu (eliminating all the nested windows, for one).
