Thanks for the suggestion, 
It is a good idea, but the problem is there is no good way yet to propagate configuration to the JS side except from the custom.js in user profile.

you could listen to event 'execution_request.Kernel' and 'shell_reply.Kernel' for code execution. 
I don't remember the name of the event for MD cell rendering or even if there is one.
(this could be added)

This should be a one liner in custom.js like :


I would just warn you that it does overwrite the current version of the file, whereas what you might wish is a secondary file with another name.
save can take a name parameter, but then it renames the notebook instead of doing a copy so be carefull.

We'll be really happy if you find a good way of propagating option from profile/command line to the browser side, or at least open an IPep about that :-)

If you came up with anything you can add it to the wiki :-)
