That sounds a whole lot easier then I'd initially thought of what you meant haha
However the simple truth is that TerrainControl feature implementations are kind of rare these days which is why I'm taking a huge task on my shoulders writing requested features for terraincontrol. For example, this mob spawning script was requested by someone who would like to spawn ALL the different mobs that can be found in minecraft. I agreed with him and added the mob spawning script in the to-do list.
There will however come a time where I will laugh at the work I'm currently doing as I wont stick to denizen scripting. It wont be that long anymore before I start learning java and I personally think that changing a folder location like GlobalLootTables would be a hella lot easier in comparison of creating a whole new system that does the same thing.
Long story short I've been here all this time so there's a good chance that I'll end up applying as TerrainControl develloper and start re-writing everything. ( Aint making promises though haha )
