Because the structure is so high, if you're trying to set things on the "north" side of the loader/unloader, you can't see if all your belts and stuff are there... there's no way to see behind the loader, making it quite challenging to hook things up.

Yes, it works exactly like tall structures in Pyanodon's. There's a few mods people use for Pyanodon's to get around this issue, like https://mods.factorio.com/mod/belt-visualizer or just using the debug menu to always show collision boxes

I am considering making a "stubby" version of the graphic that is about 2.5 tiles shorter, that could be applied in the settings

I'll second that :P

The stubby version was added in the last update, check it out

Looks great!
