In the old web UI I can easily view the streams and navigate by clicking on them.
If I have one single stream called BusinessAggregate-00000000000000000000000000000001
I can see it on the Stream Browser.
Here, in the navigator UI, it's not showing any recently created streams, which I believe it's a bug, and if I go to $streams I don't see any either.
Going to $all will show the only event I have.
