I've always seen having one application opening two about dialogs that
are the same as being sloppy.
As far as I remember there was an ancient gnome application development
doc that said it was a bad thing to do.

Surely you can still do that with gtk_about_new?

Would be a good idea, but I don't know. having gtk_about_new and
gtk_about_show which creates its own widget seems confusing to me (even
now that I'm not quite so tired...). It doesn't even follow the standard
gtk convention of the first parameter is the widget to work on. Are
there any other widget functions (besides the gtk_*_new functions) that
do this?

Why can't gtk_about_new take all the extra options?

But seeing as you can't have one window being transient for multiple
windows, you're never going to get it right if you do it by hand either.

Is there a technical reason why one window can't be transient for more
than one toplevel?
