Aside from the odd name, Glitter is actually pretty good. I downloaded it last light and installed it on my Slackware 8.1 PC. I just ran it all night and ended up with 3000+ pics of pr0n :D
Anyway, there are a few things I wish for future releases. The biggest thing would be (and maybe it's possible to do this with a hook) some way of filtering _out_ based on certain criteria, i.e. <30KB or exe extension (gotta get rid of those dialers), etc. Another thing, I would like to see would be more control over what groups it's downloading from. That way I could set it up to d/l multipart binaries overnight, while doing shorter file during the day.
Overall, I think Glitter is great (9 out of 10), but I do have some hope for future features.
