Rated 4 out of 5 stars

I just wonder, why sometimes it show some speed of the torrent, while doesn't change the size of downloaded file?

About Uploads: Currently, even while downloading, client is not uploading even a bit?

If so, please, when you add the option to seeding, keep the ability to turn off uploads and seeding.

About lags: I didn't see any lags after launching torrent download. Without any problems, I could watch Youtube, while in background, I was converting a video file. If someone have old processor, maybe should he just change the options instead of giving low rates.
I am very shocked - never expected to be possible to write a torrent client in javascript :) You are great, thanks :)

This review is for a previous version of the add-on (2.14).
