If I do a search on Search All and pick the calender there are several general choices, like This week, Next Month, Next 10 days. If I click on Next Week the calender light up next week (Monday-Sunday) as it should. But if I then click Save Search As Overview it changes from next week to two choices:
Either the x-y days from today (depending on the current weekday) or a fixed date interval.
I would have expected Next Week to literally mean next week, dynamically changing so it’s always Next week.
