I already wrote an email to the GNOME usability list about finish/close. The decision to make gnome-app-install a dialog was made by the developers and not by the authors of the HIG.
But I think that is ok to use the dialog style. Since all capplets are dialogs. Furthermore I would regard it as a preferences dialog of the desktop. Using a full blown app window also adds a lot of complexity to the application. When I started my review of g-a-i we had a mixed situation: It had elemets of both, dialog and app window. -- Change "Apply"+"Cancel"+"OK" to "Reset"+"Apply Changes" https://launchpad.net/bugs/60698 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
