The UI and operational logic of the calendar interface still have a lot of room for improvement:
1. In the "Month View," today's color is not prominent enough, which is mainly reflected in: if the mouse accidentally clicks on other dates, it's hard to find where today is.
(I certainly know there is a button to go back to today, but such an operation is too clumsy. So the key point is: when scrolling through months or clicking on other dates, the original dark background "Today" should not change. A box can be used to highlight the newly clicked position, rather than having the dark card representing "Today" flying around.)
2. Only the positions of the 31st and 1st display the month, and I'll lose track of the current month after scrolling the mouse wheel a few times.
