Could this bring the power of the command line, to the GUI?
An interesting idea, I wonder how it works from a security and flexibility point of view.
One reason I enjoy the Unix Shell is it is very easy to solve problems with the vast and expandable workbench provided. And to automate various tasks quickly, not to mention many good programs are extensible/scriptable :-)
The only sad thing for new users of traditional unix-likes is that the interfaces are often different, such as Emacs Lisp Vs Vim Script, Various Shell scripting languages vs DOS/Windows batch files e.t.c. Although most of the best programs I've used do run on many different platforms hehe.
