    But remember commutivity! x+y to y+x is a valid transform. x.f(y) to y.f(x) might not be.

     For simple subexpressions, but something like
          +(a*b)
          (c*d)
no.  Maybe, I should restate that as
          + *b
            a
          *d
          c 

I will stop at this point, or someone will take this and start a new fad of POET (Pictorially-Oriented Expression Tool).
