Some apps still do the same, eg:

(also a great app to download everything you wanted from a site, regex selections, etc.)

Makes several connections and downloads chunks in parallel, for some sites with limited upload (their, your download) speeds per session it really speeds up the downloads.

Sadly, not much development recently (9 months ago was the last commit)

Wow, that's a throwback.
