Proposals. A group with something waiting starts open. Collapse all and expand all are on the bar.
Open Proposals. Accounts server starts open, because one row is still waiting. Three rows are under the heading: List the largest folders on / is waiting, Vacuum the system journal failed, and Measure /var/log ran. Collapse all and expand all are on the bar. The count is 3 of 3, and 1 awaiting approval.
Press collapse all. The three rows hide. The heading stays: Accounts server, 1 awaiting, 1 executed, 1 failed, and reject all 1 is still there. The bar still says 1 awaiting approval. Nothing was rejected. Press expand all, or the heading itself, and the rows return. A group with nothing waiting starts closed on its own.
Keeping only failed rows is Show only failed proposals. Changing the headings is Group the approval queue. Approving the waiting row is Approve or reject a proposal.
