[Crash] Closing last document is a problem... #22
Description
Remnant of #3 and change to Welcome/Settings pages.
It's supposed to move you to the Home/Welcome page when this happens instead of crashing...
We should only allow navigating between welcome/settings if no documents are open; however, if you click on explorer with no documents, it should just open a new document then too.
Alternatively, we can just have closing the last document as creating a new document automatically.
