ShaD is a brand new kind of download manager. Instead of accelerating your download using many stream and almost completly blocking your internet connection ShaD is downloading your files in background allowing you to use your internet connection like you never download anything. This way your downloads may not be as fast as if they were accelerated but you do not need to wait until they are finished to be able to get 100% of fast network experience (for example you can make calls with skype or play mmorpg without lag while your files are still downloading). Program usage is very simple almost intuitive, there is nothing to adjust (except for the priority if you want to have some files sooner then the other) everything goes automaticaly and without your attention. You only need 3 clicks to get it done and 1 click to get it started.
