Add the possibility to scan and add automatically fresh trakers from a list like this project https://github.com/ngosang/trackerslist

So you will always have updated trakers and so better torrent download

More trackers doesn't always mean more peers(and a better download). Instead, make sure you keep PEX and DHT enabled. You probably already have it enabled unless you manually disabled it. If the torrent comes with a lot of trackers(over 4 or 6), first click on one and then do Ctrl + A. And then announce. You can then remove the offline trackers or ones with very few or no peers. Having over 8 or 10 trackers added to a torrent isn't going to make much of a difference for the peers you find. I usually keep 3 or 4 trackers at most on my torrents.

You can also have Tixati automatically add trackers to new torrents but this feature cannot automatically fetch a list from a website.
