Yeah, i think so too. I'm 12 years old right now and i try to help people in TPT but there are too many noobs. But there are people who are moderators and good people who understand follow the rules.
I think having a layer that you can draw on just with the decoration tool behind the element layer would be great, so you could make hills in the background of a city without having it interfere with people using bombs on it or having very low FPS because of the colored element that does nothing.
