Right now, drop downs allow you to use pre-determined durations like 7 days, 30 days, etc.
One major thing I miss from Google Analytics is the ability to select ‘28 days’ as a standard, month-like time frame. This is especially useful when comparing to prior periods. A 30 day time-frame comparison doesn’t work for that as weekly traffic patterns will skew the data.
Of course this can be done manually, but I’d greatly appreciate if this were available ‘out of the box’.
