Admittedly, I rated it strictly. 3.49 stars fits.
Fade in of the videocapturebox has a perceived success rate of around 90%. Switching the function on and off at the symbol works 100% reliably.

I find the handling and behavior of this videocapturebox extremely nerve-wracking! "Extreme" because I am very sure that the accessibility of the links can be made much more stable. I can't find a way to automatically clean the videocapturebox from clicked download assignments even though they are still added to the download manager's main window

Why are the captured links not graphically detectable or operable in the symbol of this addon? The on / off window in the symbol would be more ideal (with "autohide" or "autoclose" if all entries were assigned to the download).
