This is a world edit command that I find people will love.
When you do //up 1. It will place a glass block on your current Y axis and put you on top of it. If you do //up 100. It will put the glass block 100 blocks above you then place you on top of it.
Ex. I'm on a Y axis of 60. If I do //up 100. The block will be placed on the Y axis of 160
The main use for this will be adding new layers to a plot rather than just building 2 towers up 50 blocks.
