While testing out the workspaces function of Hub, I have discovered on the "Content" section of your dashboard, you are unable to filter content to just your organization, only to "Content I own" or "All Content". This is at odds with how other ESRI products are organized. There should be a 3rd choice to filter content to your organization.

Being able to filter content down to your organization allows for easier access, and would make it easier from both a user and administrative perspective to access, view, and edit content, as well as avoid duplication in your organization.
