Is it possible to have an option to disable the sapling drop? That way you have to craft saplings if you want any. Alternatively is to put in a chance factor for a sapling drop so that it only drops 1%-300% of the time. This way you can still get some saplings, but not from every tree chopped down. (The 300% is simply to allow the mod to continue dropping 3 saplings for every tree chopped down.)
Currently, when I clear out a forest for expansion, I fill warehouses with the saplings just to get it out of my inventory, and with 2 - 3 saplings dropping for every tree I chop down, it becomes just too much.
Just an idea, but also a request.
