Something I longed for during my transition from Mathematica to Maxima was
a translator that acts like a filter, that is, schematically, you copy the
(simple) expression into the clipboard, and when you paste it into maxima,
voila, it's a Maxima expression...
I used to do this also for comparing results, in fact, I still want to
compare results from time to time.
I did transition without the help of such a tool, but I would have liked
it very much. Bon courage!
