Requirement analysis for User Profile features

It has been in our planning to have user profiles and features related to them. Those features would include...?

- Create custom listings, selecting specific trees/hardware to be shown
- Share custom listings
- Create custom tree/hardware details, with pre-applied filters
- "Follow" a tree, receiving updates on new checkouts, issues and incidents for it
...

For further discussion

Start by reviewing the proposed user profile, custom listing, sharing, filtering, and follow features in this issue and its discussion. The scope is not yet defined; done would require an agreed requirements document that identifies which features and behaviors are in scope.
