• Ability to add more shift instances on busy days
  • Do those shifts fall into pre-defined time slots? Usually, yes...
    • (A) They always fall into standard time slots due to labor contracts.
    • (B) It should be possible in exceptional situations to take a late shift and expand it 1 hour.

We can make (A) the default behavior, but then give them the ability to mess around in the spot roster screen to do (B) by clicking on a shift. Like Google calendar.

More reqs in comment 6.

• Ability for the "now" time to advance manually (= user is in control + easier to test and demonstrate effects)
• When the "now" time advances
  • For definition of history/tentative/draft/future, read documentation
  • All past shifts are marked as historic: they can't change any more
  • The tentative window size always stays the same, so some draft shifts become marked as tentative.
  • New draft shifts are created according to the rotation template?
