Good add-on. It does exactly what I want it to. The only thing that bothers me is that I cant get rid of the "Download Started" notification. Leaving the timeout field blank does nothing.
Edit: After the author fixed the issue I'm changing my score to 5 stars! Now it is just perfect for my use case, plus the author is dedicated and responds quickly. Great stuff!

It's good.Thanks.
