Lacking good browser...
I love this program. Its UI, multitude of protocols supported etc. But for being a good filer a good browser with download option is missing. This program has one but it cant do even a simple http auth. Not to mention cookies, redirections. Basically if you want to download something from a site where you need to login or the download link is not straightforward, forget about it.
Its automatic 5/5 if the browser becomes as good as it is in "Downloads HD".
