Today you can add additional filters via JSON to any table, chart, etc using some of the intrinsic functions like: "getUserTeams()". With the ability to customize the user data-model (like a profile), it would be beneficial to access other user data properties to filter on that we added custom. Perhaps a new function like: getUserProperty("myCustomProp") to use in rules: { "property": "github_user_id" "operator": "=", "value": "getUserProperty('my_github_user_id')", }
