Given that this is the case, and that it sounds like we’re headed towards a world where the sidebar becomes the default, I’m not sure this is really a bug anymore. Perhaps it’s eventually how we want things to work (in which case, I think the copy in the menu is what will really need adjusting).
But if folks think it is a but, then I’d say the expectations we captured above are what needs to be met.
I’m personally OK pausing the conversation here since the sidebar is meeting my need and letting this topic serve as a reference for future discussions if it comes up again.
