At times, I can be working on one card, when I need to look at a different card. Am I forced to close the card I am working on to go to another card? I have missed things because I get a call, for which I need to abandon what I'm working on to look at something else. If I could have multiple cards open at once, it would save me so many headaches. I am constantly multi-tasking so I may not always remember what I was working on when the phone call came in.
