Feature request: let users define the time of transition to the next day

Context: It is quite common for me to work past midnight, say until 1am. On those days, I find it rather frustrating that, at midnight, my “focus list” is suddenly populated with all items of the next day.

Feature request: would it be possible to add a setting “day starts at <user-defined-time>” which lets the user set the time of the “next-day-transition”. This would be consistent with the fact that the user can also set the start day of the week (Monday vs. Sunday).
