[Usability]modal vs insensitive dialogs

[Jacob Perkins <jap1 users sourceforge net>]

Seahorse has lots of dialogs for doing various operations. These
operations can only be performed one at a time. Currently, to ensure
that the user cannot try to do multiple concurrent operations, any open
dialogs are made insensitive during operation progress. However, it
seems unlikely that users would really have many operation dialogs open
anyway, and insensitive dialogs can be ugly. Modal dialogs would at
least have the benefit of being able to show the user what can and
cannot be done concurrently.
So, would having modal dialogs instead of insensitive dialogs be a
better solution in terms of usability and the HIG?

Thanks

PS
If you want to try it out, release 0.7.2 on gnome ftp is much more
stable than cvs HEAD atm. And feel free to submit any other usability
bugs you find.
