I started using groups for when I am on buildduty (which happens every 8-10 weeks) and I find it very very useful.
I match my todo list on my little paper notebook to each group and scratching it on the page means closing the actual group in my panorama.
Here is the screenshot. Let's see how it looks by the end of the week.
