Hi, this looks interesting! Some notes from trying it out:
Recipe for copper sulfate solution is missing I think
Position on the space map is on top of Fulgora
You can get rid of the duplicate recipes for platinum plates by making a new recipe category for furnaces+foundries, I did this earlier today for my own mod, code
For the catalytic chem plant and the pressure lab you could use some of the graphics from Hurricane here like the stager or the oxidizer
Seems to cause stuttering / skipped frames when I run this mod and load a game with a multi-planet factory. I think it's because you're calling find_entities_filtered for every surface every second. I had the same issue in my mod AutoSwitchTechs because I assumed that calling that function would be fast but apparently it isn't. I had to fix it by caching the labs and clearing the cache when stuff gets built/destroyed, here is my code.
Some items don't have a subgroup so they're showing up in unsorted tab of factoriopedia
The new boulders need locale strings, or set them like .localised_name = {"entity-name.huge-rock"} to reuse the names from Nauvis
