Renai transportation adds belt ramps - they show up in the planner. I don't think balancer made of those will work, probably makes sense to filter them out. Tenebris (prime) adds bioluminectent variants of everything, including ramps. Probably makes sense to add a checkbox to select either those variants or regular variants.

Having all those variants results in a very tall dialog window - this adds a scrollbar. And for whatever reason something adds a second scrollbar that scrolls the whole window including the header. Possibly related to other mods adding their widgets on the top of the screen and factorio adding its near the bottom.
