We often end up changing / testing a lot of different geomerty within a forest object, and with a file with 5+ forest objects with 10 geomerty objects each, the forest_templates layer often end up filled with unused proxies, xref, or actual geometry. This bloats file size, increase load/ save time and it's a tedious task to clean it up.
I read that forest automatically deletes the unused geometry, but I'm not sure and I found some files with orphaned geometry.
Would it be possible to add in the forest tools, or to provide a simple script doing the following :
List all the objects in the forest_templates layer, and delete (or select to add a validation step) all the objects not referenced inside a forest object.
