Elane

To install this skin, extract the contents to C:\Program Files\Rocektdock\Skins (program files x86 for 64 bit users) then go to dock settings and choose "Elane" from styles.
Thanks to HackThePlanet for typing that out for me.

Might work for Object dock too. Who knows?

_{Used the SimpleLight RocketDock skin to get the dimensions, hence the preview may have been in there for some people.}
