We've had a few requests on our facebook page
for us to add a portable mode or release a portable version. For TorrentRover to be portable it would have to save all related files and downloads on the same disk. This is especially useful for you if you want to bring TorrentRover with you on a usb drive of some kind.
We are currently investigating this feature, and we'll probably try to implement this feature after we are finished adding language support. We'll report back when we know more.
