I look at Vueminder mostly on my PC and my phone, but an important feature for me is the ability to print out monthly calendars for the next six months and keep these in my briefcase. It's the best way I know to quickly scan my calendar for important events and deadlines, and to keep an eye on overly busy periods and periods when I will have some slack time.
A really nice feature of Vueminder is that these monthly calendars show events for the entire week at the beginning and end of the month, not just the days during the actual month. But it would be useful to me to differentiate those extra days (before the beginning and after the end of the month) by having them shaded slightly. The on-screen calendar does that, but the printed copy doesn't. I've figured out a few workarounds but they're pretty clumsy!
