>You can apply tags to blocks, which make them a kind of thing (a project, an author, a quote, a thought).

Possibly worth pointing out that this is a Logseq thing in general, and not specific to the DB version. And I agree it's pretty great - I don't use it often, but it is very handy when I do. Much more usable than YAML frontmatter, which requires dedicated pages for everything.

I think they are talking about the new newtags feature: https://discuss.logseq.com/t/introducing-newtags-with-exampl...
