3. click "Search plugins..." on newly appeared Search tab

4. click "Check for updates"

5. click Close

6. search whatever you want. Make sure you order by Seeders

7. BONUS: use "download in sequential order" (when downloading new, or from right click menu) to stream your movie and play it in VLC or MPV
