First off, great plugin. Should be standard WordPress functionality, IMHO. However, I have one minor issue. We schedule our posts every 45 minutes on one of our sites, but the calendar view rounds all times to the prior hour. This makes scheduling in that view very difficult for us, and it's something that would be really great if the calendar actually displayed the full time (or at least offered this as an option). We actually plan on increasing the frequency of posts, so this will become an even bigger issue for us over time.
