Suggestion for improvement: 15-min-grid for snapping appointments when moving in the calendar to another time

[dexic79]

Sometimes things go very wrong and then you need to move your appointments around. Most people plan in 15- or 30 minute grids. It would be nice, if one could simply take an appointment and move it to another place in the calendar and snap it to :00, :15, :30, :45 instead of only to the full hour and then edit it again.

Thank you!
