Thank you for the release!
After messing around with it for a while, I have two improvements to suggest (if they’re not already on your roadmap):
1 - Add the option to export the current selection, like you can in 3ds Max
While it is relatively simple to isolate that selection and then export it on Archicad, on large projects it can take a while for Archicad to re-render the whole thing once you make them visible again. Exporting the selection instead of having to hide everything else and un-hide them again would avoid that hassle
2 - Export Hotlinked modules as instanced meshes:
Right now it exports every single module instance as separate geometry, using instances (hierarchical or not) could bring significant performance (and potentially workflow) benefits. This is particularly true for affordable housing project when you sometimes have hundreds of repeated units. It could be tricky to handle nested modules, though.
