Use case: I have multiple booking pages in Proton Cal. I am traveling out of town for 9 days. How do I quickly tell my booking pages to block off that 9 day period as unavailable? There's currently no way I can see how to turn off days other than creating events to block out that time.

Booking all day events for 9 days would be annoying, and what if I go away for a month? Then I'd need to create 30 all day events? Would be good to have a button built into the calendar maybe close to booking pages to manage days you are unavailable. You'd click the button, a calendar view opens up, where you can toggle on or off days as unavailable days. You could also setup reoccurring unavailable windows (example: I'm unavailable every other week, or on the 25th day of every month, or every 3rd week of the month from tuesday to friday etc). The calendar view would communicate the global state of all available/unavailable days (for example: any unavailable days could have red circles around the date in the viewer).
