I love the outline feature and use it exclusively. I never want to see the stats (well, 99.99% of the time), so it’s just a minor nit when I have to open the info panel and click the outline tab with the mouse.
I’d love if there was a keyboard shortcut to open the outline pane specifically, like Shift+Opt+Cmd+i. Another option would be if the app remembered my last selection, even after I quit the app. I noticed that it does remember what pane I had selected before, but forgets when I quit the app.
