From the public project list, you can pin (or unpin) projects that you're not part of. You should be able to pin any project, even just other people's projects you're interested in.
Right now we show the pins, but they're disabled. We should have the backend support to pin public projects, so let's add that functionality in. If, for some reason, this is unsupported on the backend, then we should hide the pins completely.
