Excellent. ^^

Thank you always! Philipp Kewisch.

Nameless calendar occurs on left calendar selector/editor
After naming that calendar to "Trash",
I send schedule or task to delete it to "Trash" calendar.
If usually I set Trash calendar to unselect on left calendar selector/editor,
Schedules and Tasks which sent to Trash calendar are not seen usually. ^^
Because this program uses a surprising tweak, I laughed for a while. \O/
