Hi jacobdesigns,

If I set the application to Redshift in the Render Settings, the same four-part palette appears, as in your image.

I have no idea from which release you have updated to 2023.1 has that menu.

To answer your question, you can build your Windows and fill them with palettes. These palettes can have all the icons in the Command Manager. When assembled, you can set them in a vertical direction and use the Fold Pallete (right mouse click on the palette.
You can save the palette, integrate it and save the Layout; otherwise, after one layout change, it will be gone.

I stay on the standard Layout pretty much all the time. Perhaps setting shortcuts is much more efficient.

More about customization

All the best
