More Detailed Descriptions and Wrong Way Round Warnings

Just got the game a couple of days ago and loving it!
However I kept on running into a problem of which I have only just found out why it would not work. This is when the conveyor belts are placed the wrong way around and it does not tell you that they are. Because of this I think that there should be a warning when conveyor belts are connected to two stations but they are placed the wrong way around because the small arrows are not prominent enough.
Also I think there should be more detailed descriptions for structures and upgrades because when I started playing I did not know what benefits there were to stuff like the power plant!
