GridMapper v1.0

In the continuing list of things I was wishing for 20 years ago, and am getting a chance to check off now, here's GridMapper: an application for Windows that lets you create old-school dungeon complexes in the quickest possible fashion. Start with a filled-in underground map, and from the first mouse-click you're clearing spaces for dungeon rooms, corridors, etc. Additional options under "Tools" allow you to place doors, stairs, and walls. Save, open, print, resize, and copy your map to other image-manipulation software.

I've been using it for a few weeks now to make my own dungeon maps, and I'm finding that it greatly speeds up my ability to jot down ideas, experiment, erase, and play around with the layout. (Also thanks to Al-Krelaan's excellent HexMapper for some inspiration.)

Now, this is Version 1.0, and frankly it's doing everything I need it to at the moment to increase my productivity (and generally make the job more fun), but conceivably it could take some feature expansions in the future. Here's some initial ideas, and I'll let you tell me which ones sound most appealing:

1. A free-floating toolbar in its own, separate window.
2. Objects such as statues, trapdoors, water, etc.
3. Loading custom icons for the various features.
4. Automated random generation of corridors, rooms, etc.
5. Possibly better error-handling code throughout.

A few things that I would not ever expect to add to this application are: (a) irregular, diagonal, circular, or cavernous rooms and corridors (the program is simply not set up to deal with anything other than single-square elements), nor (b) annotations like text, room key numbers, etc. I think any of those items are best produced by standard image-editing software, and when I want fine-grained details like those I just copy my base map into Photoshop and go at it from there.

Have at it and tell me what you think!
