I'm a newbie so be gentle. I have a master checklist that I use to do event planning. That is the first list on my board. Then I have events on my board. Each event is in it's own list so we can track things we need for each. When I open my list for new event, I can no longer refer to my master check list on the board. Only one thing can be open at a time. Is there anyway to view both so I can check items against what we already have for that event? The way I can open two web browing windows or open two emails side-by-side?
