I don't seem to ba able to find a "Open Dock" Internal Command. It would be great if there was a way to have a "Games" icon on a dock. When clicked, it would open a completely new Dock that contained all the Games icons.. Then maybe the first or last icon in that Games Dock would be an Icon that utilized an Internal Command "Close Dock".

Am I missing something. I bet this feature is already in here and I just haven't found it yet. Can someone please point me in the right direction?

What you are talking about is called 'sub-docks' and is already available in Nexus Ultimate/Winstep Xtreme. Like menus, open sub-docks are dismissed by clicking anywhere else.

You're out of luck if you're running the free version of Nexus, however.

I've got Ultimate... and I see the SubDocks.. where they are vertical under icons. I was wondering if I could open another dock with a click of an icon.

You can set sub-docks to open parallel to the parent dock, if that is what you want:

Right click the Nexus control icon -> Dock Properties -> Position & Behavior -> Sub-Docks button -> Change 'Always perpendicular to parent' to 'Always parallel to parent' or to 'Always horizontal'.

Alternatively you can also create new, independent, docks and leave them floating (NOT docked) on the desktop, turning on auto-collapse - when collapsed, they will show only the Nexus control icon (which you can associate to any image you want, by the way, just like you can change the icon of other dock items). Double clicking the control icon expands the dock to show its contents.

Wow.. this is crazy. Quite impressed after using OD for years. I'll never look back.
