These features were supposed to be part of the previous build - but this completes the first build in the list of "Upcoming Builds" - "Basic Fixes & Improvements."
This build allows you to set the default Floor and Wall textures for rooms, which should make texturing dungeons much easier. In addition you can set the default Wall Height, which makes the wall height feature much more useful. If you want to create interiors, such as Inns, a Wall Height of 2 might be good in order to place rooms close together and keep the wall thickness down while the default of 16 works great for dungeons and castles.
To change the default floor or wall textures, simply click on the one you want to change and then click on one of the textures in your Library. To change the default Wall Height, edit the value.
The defaults are saved when you exit the program so you don't have the change them every time you wish to edit.
The next build, "Tiled lighting," is now in progress.
