Feature description

I would like to be able to hide selected hours from being displayed in the calendar view as they are never used and take up a lot of space.

Why do you want this feature?

I sleep from 22h00 to 6h30. I never have any events or tasks during these hours yet they account for 30% of the day and take up a considerable ammount of space on the screen. Yes, I can zoom and scroll to try and center the calendar but this isn't very good UX imo.
It would be very nice to be able to not display these timeframes to focus on what's important during my day. I think this feature could be even more useful to shift workers who would have to scroll up and down because the entire center of the calendar is empty.
