More commands for editing/making them easier to use and villager paths

I think using commands such as /fill and /clone should be easier to use so maybe make a block just like the one that can be used for structures where it will should what it will look like when you use the /fill and /clone so it will show the surrounding area when its set to clone so you can see whether you will like it or not so you don't have to destroy and redo as well have the rotating options.

There should be a world fix command for areas that are generated weird because its difficult making a weirdly generated areas look natural again so if it would like level the area.

We should have the option to show the names of past saved structures and have the option to save them to your console like normal saves because some people like making structures in separate worlds to see what it would look like.

I think villagers should have a auto recognize feature or something to let them use new paths that you make because lets be honest the paths they make aren't the nicest.
