ctrl+n for new map, and you can remove fields now. tomorrow i plan to implement undo and redo at least
things left to do before i wanna release
-editing fields
-adding entities/fields from a window
-undo/redo
-quick swap between main map and battle map
-poke file generation
things i have planned but won't do until after release
-try and work scripts into it somehow.
-make the dang thing run in a windows form window i can put a toolbar and menu bar on instead of drawing it to the screen and reinventing the wheel. there's a ready to go c# example of a XNA viewport control you can put on a form and it does its own update/draw loop but i couldn't port it to vb.net tonight

-look at using a runtime content pipeline compiler (theres lots of free examples of it around) so people can import content in the editor and have it go in the right place with the right settings
-pokemon file generation (i think types have base stats too so there's probably a way to calculate what a pokemon's stats should be based on some parameters so there can be a pokemon generation wizard (as cool as it is to be able to set them its a good idea to also have an easy way to know if its anywhere close to balanced without knowing a lot about the pokemon stats system)
