I had a couple of ideas for possible improvement on /b dome, the first of which would be the ability to make an inverted one. Currently, dome brush works by doing /b dome|/b #|/vh #

Now, I know nothing about coding, so let me get that out of the way right now, but I think the most intuitive way to access this would be to allow /vh to accept negative vaules. This way, you could get a size three upside-down dome with /b dome|/b 3|/vh -3

Secondly, and this has actually been an issue since, at very least, I was first given LS. Domes can't currently be made with a data valued block, such as wool, leaves, and stone bricks. I have to say, it does get tedious having to do a replace afterwards. Would there be any possible way to implement a c performer to this?

Confirmed and targeted for Release 5.168.0
