I changed a little bit the code of another Cargos Necessary Script and I think that you can read it also.

http://userscripts.org/scripts/reviews/79279

With those changes, cargos neccesary are shown in all pages under the officers pics, so, it gives you an idea of "when" to send the cargos.
I changed also the name of cargos for space reasons. I call large cargos LC or C+ and small cargos SC or C-.
Thanks, see you.

Nice script, work very good, I really like it.
