It would be great if either the current/estimated total fuel cost per unit shipped on a blimp were shown. Buildings that are far away cost a lot of fuel to ship to your colony, and can be a net loss due to fuel consumption, despite the tool tip on the building showing a net revenue. I know the fuel is only a marginal expense, but its difficult to eyeball and estimate the fuel cost since you have to estimate the distance to the colony and figure out the cost of shipping the materials.
