How to remove "Audiuo Spectrum" display?

Above the effects stack and below the project monitor is an “Audiuo Spectrum” windows. How do I get rid of it?

Is there any way to de-select SINGLE-WINFDOW mode like in GIMP? All I really want, for my current project:

Project bin

Project Monitor

Effect/Composition stack

Timeline

If this is about Kdenlive, you should be able to choose different layouts, as well as create your own, and select the components you want to view.

The Audio Spectrum may be hiding here:

Once you have selected/deselected the items you want, you should be able to de-dock all these components and have a multi-window setup, which you can also save as a custom layout, so you can switch between windowed and un-windowed modes. These won’t save their positions under a Wayland session (I assume it will in xorg), so something to be aware of.
