In the "All proposals" view I noted that some proposals (obviously very new ones) are preceded by a star, e.g.
at this moment. What does the star mean?
The asterisk indicates that a proposal has NOT yet met the Minimum Activity Requirements for Area 51.
The asterisk (*) was originally visible to employees only so I could see which proposals were still in the submission process before I spent too much time vetting their content. I found it really useful, so I suggested making that information public to help remind folks (and the author) that the proposal wasn't quite "done" — that it was still subject to removal if it does not complete the minimum submission requirements.
There could certainly a better UI to make that clear, but this was a lightweight addition I requested predicated on it taking little-to-no dev resources.
