At the bottom of each Logseq page, there's a "Linked References" section that just lists every use of that page tag in reverse chronological order. I can collapse any heading if I want. I can review it very quickly and find out what I thought was important last time I was working on that topic. I can also filter by other tags so I can narrow it down to "[[this tag]] and also [[this other tag]]" if my interest is something specific.

Works great for my purposes. Doesn't need any improvement for my use.
