Delayed lockdown

[patrick-nicodemus]

Idea: The lockdown menu should feature a delay box, so that users can say "I just want to do this for 10 more minutes" and then the lockdown is enabled in 10 minutes. It's easier to commit to something in the future than in the present.

You can already do something like this with overrides, so it's arguably not necessary. But from a user interface perspective this is less obvious. I don't think it will occur to most users that they can start the lockdown now and then immediately override it for 15 minutes.
