The view (page you're creating) can be anywhere, it's just the app itself that is pointed at a higher place. Conny's option, work views, should also work. Work views operate completely independently of the project browser, so you can include whatever projects you have access to. The catch is that you can't share a work view with others, so anyone else who needs the same view would need to create it and save it for themselves. Work views provide some interesting options, and I think they will continue to improve.
One other catch is that if you operate with more than one workspace (we have a few), the list of work views is visible across all workspaces, but only renders information when used in the correct workspace. I've taken to including identifying the relevant workspace in the name of each of my work views to avoid confusion.
