I created a PR for the above change. We might also want to take a look at the other ui preferences and see if we want to make them persistent

1. fullscreen: session
2. panel: session
3. nav: session
4. toolbar: session

I don’t quite understand the reasoning here, since other layout changes are preserved. For instance, if you resize the sidebar, close the tab, and reopen Storybook, that setting is preserved. If you’re going to preserve that, why not preserve the addon orientation too? Seems very equivalent to me.

Edit: I’ll also add that I always switch to the right-side addon orientation, because I feel it’s a nicer layout and a better use of space (no scrolling for my table of controls), so I’d prefer some way of Storybook remembering that, whether its in local storage or via an explicit setting.
