Thanks for the swift inclusion of the Belt Balancers, and the auto placing feature! The version I was trying to fix had a lot of problems, so this saved me so much work, I was able to release the Picker Replacement mod earlier than expected.
I also added this mod to a modpack containing most of the 1.1 Picker features (so it's mostly just a QOL pack).
One minor nitpick is that when scrolling through the list of blueprints, the belt brush orientation is reset to facing north, while the original Belt Tools mod kept its orientation. It's a very minor thing, but a notable one that would nice to fix. From my testing, (and excluding underground belt support mentioned on the Information tab), that was the only real issue. Pipe to ground support would probably be similar to underground belt, and I think you were also able to do it with inserters, but neither was never a critical feature for me (compared to the main brush and balancer)
