The mod is updated for 1.11, and should work without problems because it doesn't use the (as-yet incomplete) mod support, it just overwrites the game's core data files the old fashoined way.
|how did you control which tab the structures went into?|
Which tab they go on is based on the sN_ prefix on the model files themselves, where N is 0-4 or 99. 99 puts it on misc, while 0-4 sets it to one of the built-in styles (the ones with the same number as you picked go on the tab for your current style, the rest go on the other styles tab. If you have two models with the same name and only differing in that prefix, only the one will appear that matches your current race. I'm not sure what would happen if you're using a third style in such a case (it also depends on what kind of part you're using).
