Review for DownThemAll! by bazdalikalo
Rated 4 out of 5 stars
Every download manager I've ever encountered has a date (added on, time, or similar named) column so you can track when you have downloaded something.
It's baffling that DTA after all these years haven't got something simple as that. That's the only thing I'm missing the most in this great add-on.
