I think the auto update interval selection would be very handy. (especially to turn it off :P)

What does the timeframe selection do? only show incidents that are younger than the indicated limit? In that case it could be part of the filter box. (or part of a filterable column, extending Uninett/argus-htmx-frontend#144, at some point in the future). But it does not have priority for Geant.
