Postitioning of bag bar

[Uncle]

Hello, happy interfacers,

I'd like to bring up a small issue that I seem to be too narrow-minded to solve by myself.
It's about the bag bar or, as it is, button bag bar of nUI's, which unfortunately is quite in the way.
I can well reposition the "original" bag bar by using the movers option ( though to no avail as it is not visible), but seem to have no grasp on the above-mentioned.
Can someone please give me a hand in this?
Do I need to change some parameters directly in some .lua file or is there an option that in any way toggles the parameters responsible?

Greetings,
Uncle
