New multi app supporting sidebar navigation

Summary:
This diff changes the sidebar navigation, fixing a bunch of issues:
It will be possible to quickly switch again between the same plugins in multiple apps
No need to expand-and-check the app dropdown until the app is connected
No need for ugly fallback selections if some app connects faster than another one
