Long Events not correctly displayed on small calendar?

Hiya and thank you for this incredible tool!
I am having two tiny problems though: Although I set long events to be displayed on the small calendar on each day slot, they do not do so in the widget. They only appear on one of the slots. The function works great on the full calendar.
Second, I would love to be able to book single days of multiday-events. How might I make that possible?
Thanks a lot and keep up the great work!
Best,
Tassilo
