I'd love a bit more control over the availability settings. For example, I have it set to check my calendars, but when I have all-day events in my calendar, like someone's birthday, it shows me as not available for that day. I would like to set it to ignore all-day events at a minimum, to avoid this issue.

It would also be ideal if, when checking the calendars for availability, it could take the event's location into consideration. For example, if I am at an event from 1-2pm, but the event is an hour away, then I won't be available for a meeting until at least 3pm. I have set the scheduler to put 30 minutes of free-time on either side of a meeting, but that doesn't help with my personal calendar events.
