%expression editor
I would like to have an interactive editor for expressions that would allow me to see directly the automaton it builds. Actually, it would be nice to be able to specify what algorithm to use to build the automaton. And why not being able to see several translations: you'd have radio buttons to select what automata you would like to see built interactively.
We need a means to specify the context: another field would be nice. See
%context
.
