Looks good to me @shizzard . I'm not sure I understand the module name user_default though? If it's only only supposed to be used when debugging or introspection... maybe something like introspection.erl or something? As it is, the module sounds important, like it's a core part of the normal node execution.

in any case: since I don't really know how i will be used, I could be off base on the naming! I defer to you what's best.

@JamesPiechota the name is indeed important: docs.
I'll check the shell_default though, I missed that entirely. If those are mutually interchangeable, we can go with shell_default.
