Easily Changeable Calendar Sets

The calendar Fantastical has a fantastic feature that allows you to create specific sets of calendars. So while I'm at work, I might look at everything to do with work, clients, scheduling, and the like, but then, when I'm home, in a single click, I can add my family's calendars and social events. You can even have it change automatically by time(s) of day or maybe even location(?). It’s VERY cool — the calendar is much cleaner this way, and the change back and forth is really fast because you don’t have to hunt down each individual item to turn on and off. Hope you’ll consider this! Seems like relatively simple coding (compared to much of what you take on, anyway) for a great user-experience upgrade. :)
