well, calling it download manager would be a bit abusive, considering my need.
my request is a script that could create folders with the contact's email and separate within them the files i receive from each contact, so that i could better keep track of the downloaded files source.
file transfer plus plugin i think has that feature, but is way more complex.
there are also other good feature that could be implemented, like the ones discussed
here, but that could be for a future development.
thank you
