First of all, excellent mod.
Not having to plan the nuances of each belt, especially if I just need something quick is wonderful.

Right now, there are two options.
1) Above ground belts only.
2) An algorithm that very much prefers underground belts, even when they aren't needed.

I usually prefer my belts to be mostly above ground and to only dip under when needed.
This is partly aesthetic and partly useful as I can see the contents more easily. Back-to-back undergrounds tends to obscure things.
Not to mention the increased cost of underground belts.

Any chance on this 3rd option on the horizon?

Huh, that sounds like an interesting idea to implement. I already have an idea in my mind of how to get that done, will give it a test later tonight :)

Thanks for the suggestion!

Wish granted!

Try with shift + alt + left click on version 0.6.0 :D
