we recently had a "Library" feature where the user could explore the content on their node.

Things I liked about Library:

Easy to access (it was at the bottom of the sidebar)

Sites were sorted by recent activity

You could see sites that you have browsed but haven't yet joined or followed.

Things I didn't like about Library:

Limited customization options for filtering/sorting/presentation

Not great for diving into a single site

Recent activity text did not explain very well what was the activity

The list of docs inside a site seemed unorganized (but, also I liked that they were sorted by recent activity)

Switch between "Subscribed" and "All Sites [on my node]" always felt a little bit strange
