Allow a TASK with NO TIME.
It feels like AN assumes everyone does "time blocking" and is compelled to assign a "time" to a task. I schedule Appointments, meetings, events on the calendar because by definition those are pinned to a hard-and-fast "time". But, if I need to get a task done every Monday or the 1st day of the month, it just has to be done that day.
By forcing a time - it falls onto my calendar and distorts my perception of my calendar availability for real appointments. (I can't meet with you at 2:00 because I've got something at that time. Oh wait, its just "take the trash out".)
Bottom line, PLEASE give us the option to skip the "time of day" for a task. Its NOT an appointment. (If I choose to drag it on the calendar - that's my choice)
