I was want to suggest Building Rotation but found this thread from 2012, seems it was an idea in Dev Diary in January-2012, at that time was sound hard to implement, but is it still the same today in 2016?
And I think its not necessary for 3 layers, just 1 more graphic set at least, I mean there is no rotate for north (lets suppose the current building only facing south), only west and east, both could be same graphic, i mean start small with simple feature then could be later improvements (scrum is good guys
)
I really think its important feature cuz:
* rectangle buildings can be placed in many another areas.
* optimize the walking path for workers to deposit or storehouse
* make game more sense and more beautiful, its slow game (which can be ok for ppl who play this kind of game) but don't make it boring
