[isabelle-dev] PG preferences (auto solve in particular)

[Florian Haftmann]

I'm currently asking myself whether the substructure of Isabelle
settings in the preferences menu is already carved in stone (although
only some adventurous people seem to be using PG 4 by now).

In my naive view the distinction between "Display" and "Advanced
display" is quite artifical, whereas things like "Auto solve" and "Auto
nitpick" should be better placed in a separate menu "Hints".  Or is
there a rationale I am not aware of for the current categorization?

It is well-known that autosolve sometimes struggles with unification,
e.g. in Record.thy, lemma
istuple_update_swap_fst_fst.  I do not know either whether there have
been any ideas around how this trap could be circumvented, but my own
experience suggests we should definitely try.

	Florian
