Thanks for the feedback. Have you had a chance to play with the preview release yet
? In the first release, it will be possible to schedule appoints for any interval necessary (such as 30 mintues or 6 minutes or whatever). You can change an appointment's time by dragging to resize it or by editing it in the "More" details screen. You can also interface with the Scheduler programmatically to have a form automatically add events with the correct time.
I'm not sure if that is what you were talking about, though. Are you talking about changing the scale of the time on the left hand side of the Day/Week views? If so, you are correct that you will not be able to change the interval of the time in the first release (though you can adjust how many hours are displayed), but you can bet that will be a top priority for a future Scheduler version.
Your input on how this feature should work is appreciated. Do you need absolute custom control over the interval or would a "zoom" feature that displayed (let's say) 2 rows per 30 minutes (i.e. every 15 minutes) or 3 rows per 30 minutes (i.e. every 10 minutes) be enough?
