Collapse the right sidebar (Design/Properties panel) independently

I often work with two Figma windows side by side. The left one is for browsing our design system, and the right one is where I’m designing, placing the components I get from the design system.

In this setup the sidebars take up a lot of space on both sides of each canvas. In the design system window I only need the Layers/Pages panel to move between pages and find components. I don’t need the right sidebar (text styles, position, layout, etc.) there at all.

Figma already lets you minimise the left sidebar. Could we have the same option for the right sidebar, per file or window? Hide UI isn’t a fix, because it also hides the Layers panel I’m using to navigate.
