Enter a plus one - Probeabholer or Tragehilfe
Description
Currently friends/helpers are announced on the wall spontaneously and arbitrarily. This feature would introduce an icon to the slotstatus, that indicates: an extra person is coming along. It would automatically reduce the slot number by one if empty slots are left. (If you do, please code an opt-out-choice: "Would you like to not remove an open slot?" Removing the +1 should also reopen the slot it took, if it took one.)
Impact
Every Foodsaver. A better overview for the fs, to see how many people are coming. The plus-one choice could also be treated as a request for the BV to confirm first. This would save extra announcement and messages. Acceptance would be simple and good, since people use the button for signing out regularly and would thus be confronted with the new feature.
Proposal
easy solution: Only select a plus one from the dropdown and show this icon in the slotstatus. An extra column in foodsharing.fs_abholer would be required. Perhaps a binary helper column.
more complex solution, probably less good: An inquiry could be sent to the BV, who would confirm the plus one. Already signed up foodsaver could be notified. The profile of an unverified fs could be linked by the icon.
