enhancement : public folder - adding support for subfolders

Would like to request adding a way to support subfolders in the user's public folder. At the moment public links of a user can be accessed at the url: /username/profile/public - but not folders inside this one.

This is a good suggestion. But I don't think, I'll be able to do it any time in near future as well. Currently this project is mostly in maintenance mode.

I'm open to PR though, if anyone wants to contribute. I'll review it.
