Make it so Ctrl+W doesn't close items in the sidebars

Feature requests

Currently, items in the sidebar are treated a lot like normal tabs. If I have an extension’s control panel open, for example, I can accidentally close it by pressing Ctrl+W.

I’d expect items in the sidebar to be more stable than not, and only go away if really explicitly removed: Ctrl+W I’d expect to act on normal tabs in the center view, not on items in the sidebars.

I think the feature should include how to identify note tabs from other tabs since ctrl + w on notes tab should work even if the note is on the sidebar. You then use pinned tabs to prevent them from disappearing.
