On my bb wish list:

I'd like to set my default reminder to 30 minutes so that when I quickcompose a calendar entry, it will automatically have an alarm. However, then all of my "all day events" will also have a default reminder unless I change it. for various reasons, i usually leave my phone on all night and the "all day events" will alarm at 11:30 if i don't remove alarm.

I wish that "default reminder" would automatically switch to "none" as soon as I check off "all day event".
