I also like editor priority #1. I have coded and created in minecraft many years without a editor. Only texteditor against the comunity-api Buckit.
I was frustrated to make input and output over a chat of 12 x 35 charakters. The developers never make a api / editor. I give up the game 2016.
So i am very glad to have a editor , custom window and custom dialog. ??
The editor is well done and i wait for the update 1.5 for more maps and server connections. ?
