This would be good...
[area add static "number"
So you could add a large area of grass or other tiles, or do a straight line and add a line of wall to an area.
[area delete
This would be good so you could delete a large area instead of one by one tile when you are customizing a town. Unfreeze a building and delete it, you will see.
*These can work as the [unfreeze and [freeze commands do, click on one spot and run it into a square and click on another part and a total 10x10 or 30x30 area so on and so forth would be complete in a matter of 2 clicks instead of 900 clicks (for a 30x30 spot).
Just thought I would add a little.
