In Logseq tags are pages (also in the DB version) and of course you can place queries in them. So I guess what Tana does in addition is allowing the user to setup the same queries for all the tags? In that case, have you tried the contextual sidebar?
You can add properties to blocks using “Add property” slash-command. Pages have buttons under the title to add properties. From there you can also setup a “properties template” for each class. Pages and blocks tagged with a class will get that template. When assigning a class with # you can toggle “Turn this block into a page” and what you get is something like a page embedded. Very nice because it’s what I already do manually in my graph.
