[REQUEST] Option to move source files instead of copying

[1dolla]

As per title.

As already discussed on discord channel, this feature request introduce far more deadend problems than it resolves, in the end that can be done cleanly only for very very specific use cases, and as I don't want the code to be more complicated than this is actually, this won't be done until I find an easy way to do it without breaking everything for normal usage
I don't close the issue to keep it, when I will have time to think of it, or when an idea to do this is coming to me...
