[Question] modularizing user

[johnadvincula-ada]

Hi Ryuta, Thank you for your awesome talk.
I would like to ask your suggestion on modularizing user module?
each user type can have one module? let say admin module, customer module and merchant module?
or all user type can be put on the user module and create one module for the role?

Btw, where do you put all common classes that are not binded/related to any modules like helper classes or utility classes?

Thanks a lot :)
