number of spell icons

[threeofme]

I've just installed profitui_reborn. I am trying to customize the spell icon hotbars. The default displays twelve icons, eleven on one line and one on a line below. I would like to know if there is a way to display all spell icons on a single line. Having one lone icon on a line by itself is awkward and breaks up continuity when I have more than one bar active.

Thanks in advance.
