One thing might be useful is an orphan cleaning option, because every time you compile a document (I did it a lot) it creates a new container and it can get quite big if you don't pay attention.
I solved it with a command line in the Makefile. So if there is a way to integrate an option to launch docker rmi $(docker images -f dangling=true -q), it will be nice.
