how do I make the right sidebar have more than 1 window? as you can see my right sidebar has everything in one window with tabs. I would like to split the window so I can have laser tab and cuts/layers open at the same time
Window menu > reset to default layout
See this video for information on arranging your LightBurn workspace:
Note that your display has to be large enough to accommodate two stacked windows on the right side, or you will be limited to one.
