Click on Contact in List Item instantly Searches for all List Items with that Contact
I think it would be helpful if Clicking on a Contact in a List Item instantly did a Search for all List Items for that Contact similar to a Tag. I work this way in Workflowy and it is a great way to instantly see content related to that contact. For example: if a Contact is calling I can easily look up all of the items related to them so I don't have to manually find them.
