Excellent questions. Both of these are missing capabilities (aka bugs)
that will be addressed over the next few days. Feel free to open bugs for
these. To navigate 'back' the start eclipse back and forward toolbar
buttons (yellow arrows) should allow you to do this ... but there's a bug
that prevents us from bringing you back to the 'top level' view. In the
meantime you can work around this by clicking on the top level folders in
the outline view (crappy workaround I know).
