It would be cool if we can get a way to record us building something from a given point, without having another account.
So like if you want to make a time lapse of a building being made. You can set a camera up at a given spot, start it, do your thing, stop it, and it will save to your computer.
I know this sounds more like a mod thing, but I don't think models are allowed yet. It's kinda important to have a model so you know what the camera is looking at (Maybe a command will work. Look at something, put in the command to start it, do your thing, stop command, and it will save it to your computer.)
