My suggestion(s)

I have all kinds of ideas for different types of the current objects but I dont have time to list them all right now so I will come back to do that...

-Just something i thought about earlier today--- why not make the object buttons in a "compressed" way? I mean it like this: a single button for conveyors, a single button for copiers, etc... but when you click the button a vertical bar pops up from the button and shows you the different forms of that type of object. This could be considered an update for the UI, but it would also allow more space on the bottom for more types of things to play with. And the way I would make it, the button itself would keep the last selected option for that object.
