Ok, I'm trying to use the widget debugger, but I'm a bit confused on how it works. I'll hover over the plank menu, and the log I want to select, but how do I know which one is the parent, child and grandchild? There's three colors it shows when I hover, green, red and white. What does the 'R' and '-' mean?
I wish the api provided a bit more information... any tips?
