Code review comment for lp:~elementary-dev-community/noise/fix-1089869

Hrm, I'm not sure I like having them both removed from the welcome screen. I would expect the search bar and view switcher to be present, but insensitive here since they can be enable for this "Source" (the music library) by adding music.

Removing them when you switch to another source makes sense because there isn't a way to enable them that that source. But, to me, it still feels kind of weird. I think I personally would rather the switcher just becomes insensitive in all cases instead of being completely removed.
