I was very excited when I saw that you could use custom blueprints with this mod, but alas my dream was crushed when the foundrys placed as part of my blueprint did not have its recipe set.

It would be a massive improvement if foundrys and other production machines retained their recipe set by the blueprint.

(it also did not want to place the belts and inserters, but maybe I simply do not understand the settings.)

Oh, of course! Could you give me the blueprint string so I have something to test with? I might be otherwise limited in what I can come up myself for direct processing designs.
There's algorithm step to do drill into belt routing so it doesn't overbuild transport belts beyond where they're needed. I just didn't account for assemblers yet.

This is the one I use:
