Could someone who groks the new OmniUser interface (perhaps Bob?) 
send a few line note about cool things to check out in it?  I'm 
playing with it, and am intrigued, but still confused. Some examples 
I'd appreciate help with:
- The default view is the "alternative" syntax, but if you click the 
red button, you drop into Bob's SyntaxMorph-view.  Is there a way 
back?
- How does one create a new line of code?

Thanks!
  Mark
