I was a bit shocked to find a solution to a long standing annoyance with Sage symbolic derivatives
https://trac.sagemath.org/ticket/5711 https://trac.sagemath.org/ticket/6344 https://trac.sagemath.org/ticket/14517 https://groups.google.com/forum/#!topic/sage-devel/LIBo8nwftkI I still find my self having to explain what the Sage derivative "Pynac" notation means to people reading my Sage worksheets. Yes I am aware of the origins of this notation and it's advantages in specific situations, but something that has been this annoying to so many people for so long should have a better solution. It turns out that a solution is now "hidden away" in plain sight: https://trac.sagemath.org/ticket/18640 http://sagemanifolds.obspm.fr/doc/18640/reference/manifolds/sage/manifolds/utilities.html Apparently ExpressionNice was quietly merged a few months ago in release 7.3 as part of above SageManifolds ticket. OK, it is nice to now have ExpressionNice but wouldn't it be even nicer if it did not have such an obscure name and nicer still if it was actually the default output format in Sage? (Of course it would be good to still have the Pynac notation available as an option when needed.)
