We're introducing a new menu (https://www.figma.com/file/a1nkbWgbgjRlrOY9LVurTz/Comm-%2F-Desktop-app?node-id=1272%3A88750) that looks exactly like `AppSwitcher`. In order to do that, we're going to create a reusable component that renders such a menu. To make review process easier, I'm starting with renaming the concrete component to what will be a reusable component, so that it's obvious what will be kept and what will be moved to the concrete implementation.
