Well, now I have tested it and it works real nice... Now I just need to script it to start with OWB.
A 'Save As' button would be nice too, maybe could be done with a flag when starting ClipDown (if it doesn't already exists, I did just a quick test yesterday and didn't read the docs)?
Edit: But it still would be nice to be able to send an url to it directly from an OWB context menu insted of having to press the button!
