I was thinking it would be nice to change the Local device, Linked devices, Local hub variables, and Linked hub variables to change to a multi-select list. You miss the ability to click on a device and go to the details of that device (a feature I hate because I end up clicking on that instead of the tiny icon next to it.) However, when adding or removing devices, it is much more efficient as you can add multiple devices at once without having to OK each one. You also don't need the Shared vs. Private sections, or Linked vs. Available.
