In order to enjoy my maximum download speed, I use and like Axel very much, but from time to time I download multiple files and having so many windows opened has some disadvantages.

I use Axel with FlashGot in Firefox (Seamonkey etc) but I would like to add a GUI for that, and possibly have multiple downloads in a nice list as in any civil downloader. I am not aware of a GUI for Axel that works. Axel-kapt crashes. (A question on how to use it properly in Ubuntu got only one somewhat dismissive answer by yours truly...) Gaxel just opens a window with empty fields that I have to manually fill (which beats the purpose). I would like to know how to install something like Gwget which is described here, in an old answer as an alternative (but Gwget itself might be too old too).

(So, what I ask is: multiple-connection/maximizing-speed downloader, with a GUI.)

Help!
