Right now, when opening a nzb of collection of files, I do the following:
expand the collection, so to get the entire list
Select the first and r-click 'Test' (or from the menu bar > Option > Test)
If it is okay, then I tag the entire nzb
Idea. How about having this as an option?
Meaning to say: user 'launch' nzb, click on download, Newbin Pro will then run a test on one of the files inside - when it fails, it will not process the other files, else it will queue the files.
