Proposals. Machine is the default. Action type groups by the command kind, so three shell commands on one machine become one heading.
Open Proposals. Group by is machine. Accounts server is one heading with three rows: a waiting list of folders, a failed journal vacuum, and an executed measure of /var/log. Reject all 1 sits on that heading, because one row is still waiting. All three actions are run_shell.
Set group by to action type. The heading is run_shell, and it says 1 machine. The same three rows sit under it, with a machine column for Accounts server. The heading stays open because one row is still waiting. Reject all is drawn on a machine heading, so this view does not show it. Set the menu back to machine and that button returns. Nothing is approved or rejected.
Machine, status, and a site are Group the approval queue and Group proposals by a site. Hiding every status except failed is Show only failed proposals.
