UI proposal: Panel column togglers

Leaving as feedback despite the fact this discussion is closed. With this new feature alongside with Proposal for the “Panels” screen in Global Administration - Development - XWiki Forum I have only 2 questions:

  1. Saving panel state across sessions: I haven’t yet checked the implementation logic, but currently I notice that the state of the left column (i. e hidden left panel) isn’t preserved after the user logs out and logs back in. Should this be considered a bug?
  2. Scope of usability: This feature appears to work across XWiki pages and editing, except in the Panels Administration section. Is that intentional, perhaps due to the ability to reorder panels via drag and drop on that page?

I really appreciate the implementation of this functionality, thank for the work on usability improvement!
