Finally more librarys, that is highly welcome.
I think that every new library you put in will be more than welcome.
For Architecture - Many choices here. Bridges is one of my top wish!
For Urban - street / roadcrossings, more streetlamps, roads, sidewalks and so on.
For Civil Engineering - Wires maybe.
For Industrial - ?
Other - All that is doable, cool stuffs.
Any timeframe when new librarys will be out?
