Hi @kjdiehl,
Thanks for your feedback, I can certainly see how folks would benefit from more robust searching and filtering options. I can make a couple recommendations to help sort your existing data:
Use separate vaults for your own items and those that belong to family members. I personally have a Private vault, a vault shared with my spouse, and then a separate vault for each family member for whom I manage login items.
Use a collection to group and search vault(s) separately from each other. In my case, I have a collection with my Private vault and my shared vault with my spouse, and then a separate collection for all the vaults that contain other family members' items. This means I spend most of my time in the first collection since all of my frequently used items are there, and when I need to look for something on behalf of a relative, I can swap to the other collection and search without my own items cluttering the results.
You can also make a collection with a single vault, which means you could search that vault exclusively and use categories and tags from there to further narrow down your results.
All that said though, I recognize there's always room for improvement and we do have a couple feature requests to bring more robust searching and filtering to 1Password 8 so I'll add your voice to those. I also really like the idea of being able to tell which vault an item belongs to without opening it, so I've logged that feedback as well.
Let me know if you have any questions and thanks again for all your valuable insight. 🙂
