I wanted to pass along an idea for the smart campaign scheduling calendars. I recently accidentally scheduled an email campaign to go out on Sunday instead of Monday, and I was wondering if it would be possible to highlight the weekends in a different color on the calendar, and/or even display a warning if a weekend day is selected ("Are you sure you want to schedule this on a weekend?"). Not a huge deal, but something small to prevent these sorts of accidents from occurring in the future.
