I began playing with the editor and it's great fun, but two things really bugged me:
1) I was working on a naval war scenario with a number of islands, and several times I accidentally filled most of the map with sea or plains because I didn't realize I was still in fill mode. Luckily I had already set the regime borders, so I could trace the islands by adding a line of sea hexes around the borders and then fill the rest with sea again. I know I'm a fool, but in the absence of an undo function... do you think you could make this a bit more foolproof? Maybe a "Do you really want to?" popup, or at least changing the mouse pointer into a bucket to remind fools like me that they're about to erase hours of work with a single click?
2) Did I mention I'm a fool? So I copied the masterfile, edited some SFTypes and made my scenario load the new master. Hmmm. When I opened it again, I had somehow replaced my scenario with the masterfile. You know, all units, the map, it's all copied from the master now. I'm not sure what I did wrong...
