I've just returned from the Types Summer School, Giens, France where Proof General was used for a class of about 50 students who were learning Coq, Isabelle, and LEGO. I received many useful comments and feedback, which will be used to improve the next version. Thanks to everyone who gave suggestions and bug reports to me, including: Michael Abbott, Bernd Grobauer, Sebastian Skalberg, Thierry Massart, Darmalingum Muthiayen.
