+Subject: [PATCH] Show the account in the title bar when the sidebar is folded
+
+The Minecraft account lives in the right sidebar, so folding the sidebar
+away took with it any way to see which account is selected or to switch
+to another. While the sidebar is folded, the account now sits in the
+title bar next to the window buttons: its head and name, opening a menu
+to switch accounts, add one or remove one.
+
+The menu stands in for the sidebar's account card rather than being a
+second one. That card stays mounted while the sidebar is hidden, so the
+selection, the avatar and the sign-in dialogs are the card's own and
+stay in step with it, and a dialog opened from the menu outlives the
+menu closing.
