When last time I used Rip Tiger (with help of Giveaway of The Day) I faced following problems:
1) If there is error in connection then Download would stop
2) Download would stop due to some error
3) Simultaneous Download would affect the Speed
So I think having Inbuilt Download Manager (like Mozilla Firefox has it) will help to PAUSE and RESUME a particular download. So the shorter video can be completed first or so on.
In case of temporary error in connection pausing and resuming will save the video.
I appreciate your efforts and I would like to thank you for this wonderful software
resume the unfinished tasks when I desire
