After Net Transport became a nagging shareware, there was no other free download managers left till I saw FDM, at first I was a bit sceptical but now I a totally convinced and would like to request you to keep this software as is as it is not filled with bloated UI which makes it way more buggy.

Just add mirror share feature in the future and try and keep it free for as long as your pocket can hold but if you make it paid, I surely would understand your compulsions.
