Query: Last interaction with object / Last mention

I would love for queries to be able to look up objects (for instance relationships or projects) that hasn't been mentioned or backlinked (and perhaps updated) for a set duration. I would use something like that to help me stay on track with projects, commitments or relationships that hasn't been tended to for a while.

I guess that would require some sort of (hidden) property that displays the date of the last mention/backlink of the object. This would extend the use of queries, and thus also the value of a Pro subscription ;)

I have several ideas as to how this can be implemented in Capacities, but I think the idea in its simplest form is the precursor for everything else — and also a probable common denominator for other users.

Would be open to discuss this with members of the Capacities team if that's of interest.
