Hello, I hope there is a automation feature, if there is video type file, make it download start, end first. if there is audio type files, compressed files split make download priority ordered.
And I prefer speed limit per task than global speed limit. So set global speed limit as 40~60Mbps, and set speed limit as 60~120Kbps per task. by using wild card, or speed limit automation by script.
Or at least, please add a option speed limit per task in Tixati setting, Transfer, Files.

Please don't download torrents sequentially unless absolutely necessary. It hurts the swarm health and you may degrade a 100% status torrent transfer.

Settings > Transfers > Files > Auto-selection of files

In the priority tab you can select for example:
High stands for the priority to apply.

There are per-category limitations, do you use categories? Tuning each transfer manually seems unnecessary to me.
