I was bemoaning the inability to position the Galleries where I wanted as I have two monitors and I use the left one for my design work.
It turns out it was there all along, I just didn't know how to rev it all up.

The Galleries can be opened, pinned, with Utilities > Galleries and selecting any one of nine of them.
They also have Shortcut Keys with a mix of Meta and (F9, F10, F11) and a solo Shift+F12 (Animations).

Now you either double-click the title bar of each or drag off the pinned area so they float.
They float and remain in that place even after closing the XDA.

Double-clicking the Title repins and the repeat puts it back into its unpinned location.

Thank you Xara.
