Google Calendar -- option not to sync all-day events
If I have something to do at some point on the certain day, but not a specific hour, GTD/David Allen recommends not to schedule it for a certain time, and only use the calendar hours for strict time constraints. This is how I use Todoist.
However, when syncing with Google, this causes my calendar to be full to the brim with "all day" events which are displayed before (and more prominently than) specific-hour events.
I therefore vote for an *option* in preferences, to not sync all-day events to the calendar.
