Currently, if you are in the workspace view looking at all of the sheets in the workspace, you have two icons that allow you to browse through the attachments and the discussions of the workspace. These are really nice features, and I think they would be complimented by adding in a view there for the Update Requests.
I deal with many sites remotely, and in order to manage the discussions I can just view from the workspace - but in order to manage the update requests I have to go in sheet by sheet. If we had a button in the WS that would allow for UR view of the entire WS that would be fantastic.
