How to edit pdf properties?

[geoffm]

Problem:
I often do research based on litterature reviews, which involves having multiple PDFs open at a time. Since most authors don't bother editing their metadata, the PDF's window title (which appears in the window list, for exemple) is often pretty random and doesn't help me identify the PDF, so when navigating to my pdfs I often have to cycle through them before I find the one I'm looking for, because I don't see their names.

What I need:
Some software or hack that allows me to edit the pdf properties / metadata so I can just change their title to something relevant, (tried pdfedit, can't find any metadata editing function)
OR
Some other workaround that allows me to rename the window title

Don't tell me I can just learn by heart which is what in my window list, I constantly close/open new ones so it's too much of a mess
