I know the 'desktop' is technically a Finder display, and thus the dock 'always' displays it. The thing is.. I never use that icon. I usually launch finder windows in this manner - I click the desktop (if its not already the active app), then hit CMD-N or CMD-F or both (hitting them in succession quickly opens 2 finder windows). I already wanted it to go, but now that I see the new icon in v 10.10.. I really want it gone. How can I hide that icon from the dock?
