I would upvote improved search functionality.
My use case:
Create a list of all images (in Finder preferably) including Person A and Person B, but not Person C, taken in or around Paris France between June and September of year 20xx.
I understand the complexity of creating robust search interfaces (I’ve written a few myself) so I get why it may be a lower priority.
… in the meantime, any way I could just read the Tonfotos database from an external routine and do the searches myself? What database tech does Tonfotos use anyway?
