I just added hundreds of resources to my Logos installation. The "new resources" menu coped very well. Performance was excellent, and I could scroll up and down easily.
However, the width of the menu kept changing as I scrolled, which was very off putting.
PS - Personally I see no need to add short titles to this menu. You only need short titles if you can't see the full title, and in this case we can see the full title.
