Currently in the dependency graph's legend says Green circles represent open bugs. I think it would be better to show it as 1. Green circles represent open bugs. <a small green dot here> 2. Gray circles represent resolved bugs. <a small gray dot here> I think it'll make the view a little more nicer and gives out more details. Open to discussion on if this should be there or not.
Not sure what you are talking about, but displaying a "small green dot" besides the text which says exactly that doesn't bring any value.
