I want to repeat a series of downloads that were completed. I "removed" them from the home screen. How do I see them listed again, and how do I repeat the download? When I tried, I was given the merge/don't merge trackers, but no answer let me proceed. I'm not a skilled torrent downloader so I could use some help, guidance, please.

Main tab is Transfers tab. You can see all your torrents there. If you get an question to add trackers, that usually means that you are adding a torrent that is already active, or choosing the wrong file. Home tab is for sharing links in channels, shouldn't bother you if you don't use them.
