I gotta ask for an extension on this 
So I’ve reworked the plant code entirely to allow as many nested plants as you like. It now also supports as many plants within a plant as you like. But I just need to make sure that the GUI editor is Ok for moving things around. As it stands it messes up some text in the .csd file. I don’t think it will involve major surgery, but I’ve very limited time for the rest of the day. Sorry to keep you hanging, but it will be worth the wait
