mAYBE more docs for world composition, yes its going to be replaced but thats a ways off ? I can’t add landmass to my tiles which makes no sense and very needed, I suppose I’ll be able to work around it whne I get time but just another unnecessary inconvenience holding me back.
Also, please make it non coder friendly to fix terrains, so that I can sculpt below the lowest point. Thats incredibly agonizing that as a designer I’m stuck unable to ‘design’ 
There are workarounds for that but they are horrifically unpleasant and non real world. I hear that’s a Numbers issue, low to high, but if thats true and the power of said numbers, why isn’t there a easy way in editor to fix that. WE’re not all programmers, we need easy(ier) ways to allow our creativity to THRIVE ;z)
