[Design] Selections without focus in Chandler

[John Anderson]

Chandler, like many applications, displays more than one selection at 
the same time e.g. in the sidebar and summary view. Commands can only 
operate on one selection, the one that has keyboard focus. To make this 
distinction clear we draw selections that don't have the focus in a 
lighter shade of selection color than the selections that have the focus.

However, I've notice that people are still confused when a command 
doesn't work on a selection that doesn't have the focus. I'm thinking 
that we need to make the difference between focused selections and 
non-focused selections more distinct, and was wondering what people 
think about drawing the non-focused selection in gray rather than a 
lighter shade of the selection color.
