You can? Tell me how

You can turn it on in `View -> Search engine`. Then a new tab will appear next to the main transfers one. You can (have to?) add search plugins, which is done from the same search tab (look for a button in the bottom right). And I think to remember you need to have Python installed for the search tab to work, but qBittorrent should prompt you automatically for it.

I might be misremembering something, so ask again if something I said didn't work or wasn't where I said.

Free extra tip: did you know qBittorrent has support for themes? I got a pretty clean dark theme one, but no way I can remember the name or where I found it.

I love qBittorrent.

You can take that a step further and integrate it with Jackett: https://github.com/Jackett/Jackett
