Yes, and I've changed that text just this morning, by adding "or duration " although it currently will never be triggered.

You are still confused? Man, you should had a look at that code some months ago, at that time you would be *completely* confused ;-)

I've done *a lot* of effort (several weeks!) to cleanup these capture kind of things and I'm just a bit tired of that cleanup work now as the code was really a mess before and an annoying thing to cleanup.

"Misusing" is really a hard word, as it's almost doing what it's named implies :-)

That's the way it's currently implemented. I do agree it is a bit unclean.

Maybe I'm going to do some more work on the capturing engine in the near future, but time is rare and work is ...
