Q. How do I rotate in 45 degree increments?
A. When you put in an object, go to the toolbar and then click on the "select objects" to quit painting the objects into the area. Right below the tab for the area name at the top of the screen are several buttons: Go to Start, Show North, Reset Object Orientation, Rotate Object 45 Left, and Rotate Object 45 Right. So all you have to do is select the object and click on one of those buttons.

Q. Is there a way to create groups as we had them premade in Neverwinter Nights 1?
A. Select the objects you've placed, right click them and select Group. Name them. Right click them again and select Export. Save them into your modules directory inside the current temp folder you are working with (the module name will be at the end of it). Restart the toolset and open the module, you will see your grouped prefabs in the Prefab tab. You will have to rename it and classify it to get it organized as you want.
