Find better Name for gcr-viewer.desktop
I was looking at the list of applications in "Open with" in Xfce and one of the applications in the list is called "View file" and it have no Icon and also no Comment: https://gitlab.gnome.org/GNOME/gcr/blob/master/ui/gcr-viewer.desktop.in.in
I also see https://gitlab.gnome.org/GNOME/gcr/blob/master/ui/gcr-prompter.desktop.in.in which have both Name, Comment, and Icon.
So maybe find something better then "View file" and maybe add an icon and comment to gcr-viewer.desktop so the user have a better idea of what might happen if the user select it to open the file. Like maybe "Certificate Viewer" which is the title of the gcr-viewer dialog.
