Winstep Nexus Dock
Full user review
"Surprisingly sophisticated for a freeware app."
Excellent GUI that is sleek, fast, complete and flexible with a myriad of options and features for almost anyone's docking requirements. Similar to OSX, but better.
None at this point.
I run Nexus with XLaunchPad for a surprisingly complete Windows 7 user experience. Nice app and its FREE!
