Option to organize the Link References Filters

If you have a lot of Link References, the Filters are difficult to navigate:

An option to organize the filters would be beautiful.

Possible solution:

There could be a page specifically for organizing Filters. On the page, you’d see all your pages, and you’d be able to create a hierarchical structure for them (so an organizer page for all your pages, like a table of contents). For instance:

  • Books
    • The Art of Learning (Josh Waitzkin)
    • A Whack On the Side of the Head (Roger von Oech)
    • Mastery (George Leonard)

  • Daily Notes
    • 2021-12-11
    • 2021-12-12
    • 2021-12-13

  • People
    • Brian Johnson
    • Josh Waitzkin
    • Thich Nhat Hanh

  • Themes
    • Learning
    • Teaching
    • Movement

Books, Daily Notes, People, Themes, in this case, would also be organizer pages.

When you open the Filters, you’d see them as a tree structure, where the organizer pages are collapsible.

I wouldn’t mind if some of the attributes would become a first class citizens.

The categories could be achieved with type:: attribute.

It would be great if the tag hierarchy could be used for that as well.
