I just finished my fourth tile (2 improvements and 2 construction sites) in the workshop and I have some suggestions to improve usefulness.  If there are ways to accomplish what I suggest already then please let me know!

1.  Allow the ability to select an object and copy it.  a lot of times I spend many minuets getting the rotation and placement just right and then I want to duplicate it.  currently the only way I know of is to just start over from scratch which is quite a pain.

2.  Allow the ability to select many objects and move them all relative to each other.   I just spent about 2 hours designing a building and found out that the orientation is all wrong when I go to build it in the game; its all backwards!  sure, I can change the view in game, but, this is just an example.  I would like to re-orient the tile in the workshop by turning everything 180 degrees around relative to a central point, but, there is no way to do this without moving every single piece individually. 

3.  Allow the ability to color each object separately.  currently we only have the ability to color all objects the same color.  sure it looks nice, but, there are some ideas I have that I can't do because of this.
