Whilst I was playing in PTR2 Pioneers, I set my eyes on the Goods-Icons of the industries... and, I must say that I think they are too small.
I'd suggest that you make them 15-20% bigger. Not as big as when making a new engine-route. (these are too big, also).
It's a pity... cause they are nice icons.
Why don't you make a switch-button in the options: "big industry Icons".
Then the user can choose, if they want to see pretty industry buildings, or clear goods-icons.
