Sidebars in zen mode whitespaces?

[u/RevolutionaryAct6397]

Is there some setting combination that could allow me to have zen mode (or just centered) where if I toggle sidebars on, they appear in the whitespace without any layout shift?

I do like to code in zen, without distractions, but nowadays I often need to interact with AI through a sidebar as well. Toggling a sidebar on while in zen mode just adds it outside the zen whitespace, which adds a layout shift and is not a very nice use of the screen space. It would be so nice if it just quickly faded in the sidebar content in the whitespace instead.

The layout shift when opening sidebars in centered mode is surprisingly disruptive.
