Guys, sorry to butt in... I noticed your vertical Nexus docks are usually pretty wide, so this is just a small reminder that you can decrease the spacing between icons in the dock if you want (Dock Properties -> Appearance -> Icon Spacing button), with separate settings for horizontal and vertical icon spacings.
The default is 16 pixels between each icon (8 pixels each side of an icon). Reducing this all the way down to 1 pixel makes for thinner docks and possibly fitting an extra icon or two into the available space.
If you already knew this, well, nothing lost.
