The symbols over the bots DOES NOT work ... if hides what kind of unit it is, and makes it to hard to see the cargo as well as what's mounted on it.
As for the building, the entire design you've given us is based on queues ... and that means an FEEDER storage, and a PULL storage ... and when you start getting a good sized base going, it starts becoming impossible to keep track of which is the feed, which is the pull ... and the symbols don't work for the same exact problem, you're having to zoom in to see past the symbol to see if you haven't ran out of product.
Colorization PLEASE ... I sure hope you designed your assets so they can be colored ... this all crashes and burns and itr back to my other games if they can't. And no, FACTORIO doesn't allow coloring ... but you control IN/OUT with your belt design, and you know if you're out of product because the belt is empty!
