The toggle sidebar feature is great in Rhino 8
I did notice a bit of oddity with it (in my opinion)
-If you toggle the sidebar from a docked state it will resize your viewport window (a bit jarring)
-If you click on a panel icon of the collapsed sidebar, it will open the full sidebar of that panel and not resize the viewport window
I believe it would be a better user experience if the default behavior “floats” the sidebar/panels atop the viewport window instead of resizing it.
This would occur regardless of being toggled fully on/off or a single panel icon being selected.

Thank you!
