I have several groupings of torrents; those that are currently downloading, and then those that I am seeding, separated by groups. I would like to be able to sort each group differently. Specifically, I would like to be able to sort downloads by Progress, and seeding groups by Activity. The main reason is that using activity for downloads causes them to jump up and down constantly, which I find annoying and distracting, but I want to be able to see which of my seeds are contributing to my UL activity in case I want to throttle them back a bit, or even maybe open them up for more throughput.
I hope you will consider this feature. I love Transmission, it really is the best torrent app for the mac.
