capability to switch between screens of same program
Ability to switch between windows of the same program, for example ability to switch between Excel windows, even while in full screen mode. Its difficult to move between excel sheets while working on multiple spreadsheets
One thing that consistently frustrates me is the inability to easily switch between calendars while making events. I have three or more calendars at any given time, and if I'm not in the right one and begin to make an event, you just have to delete it and start over (as far as I'm aware) perhaps there is a way to make a dropdown menu in the creation of an event that allows you to choose which calendar you're creating it on.
I find that this is because when I use the calendar, I look at the whole week of events for each calendar, and create new ones based on the time available, rather than the calendar that I'm in. So, double clicking on say 4pm on Tuesday to pop open a new window is much more intuitive than going into calendar "Lab Work" > events > create a new event.
