I remember before that the editor used to be different. Like, when you pick the steel blocks, you can just left click and drag your cursor and create multiple walls fast. But now, it is just one unit at a time. I guess its good if you are using eraser and you accidentally erase an important door/teleporter, it doesn't happen as often. ^Sorry, that sounded awekward, but I hope you knew what I meant. But a way we can fix that is if we add an 'undo' button. Tbh, I liked the old editor. This one feels so tedious and boring to click every tile if you want multiple walls or having to erase one by one.
