Current questions and answers regarding the map editor.

I think a mod should only be called a mod if it potentially affects other maps. This is the case when you place an object and then change its properties using shared data (within the map, a clone of the object will be created with the same path, which will mask the original object). However, if you simply copy an object from the game's resources into the map's archive, give it a unique name, and customize it, there will be no problems.
