Re: [isabelle] New error messages in Isabelle 2013

I would like the output panel to remain, if at all possible. Having to click on something to see the current state is cumbersome, and if I understand your comment, it is only available for errors and not for inspection of an arbitrary intermediate proof state. But that's what I often want to do. Moreover, the pop-up windows are quite small and will typically need resizing.

It has been the trajectory of the Prover IDE for several years already, and we are now approaching the point where many technical side-conditions are settled, to make more serious attempts at structured editing support.  Isabelle2013 is just one more step, but not the last one.
