Rated 4 out of 5 stars

Slick! Easy install, no configuration. I like that I can distinguish edited instances. I do wish, though, that I had a way to make my repeat appts stick out *less* than the other appointments, rather than more -- my calendar's too busy already. Too bad there's no way to control the text color to make it lower contrast than the auto black/white -- I'd like Lightning to offer control of text color in addition to the background color.
