Other than the info in the top bar, the windows that are Pinned now are chat, preview, and activity feed. If this was the only info needed, it's already displayed better on the channel page. Some people like to be able to see things at a glance without have to tab out of thier content, to open up a pop up from the quick actions menu. Please put the ability to 'at least' have the option to pin those windows back in the dashboard as 'open'.
