Does KTorrent support seeding priority based on the torrents share ratio? I mean, if you are seeding 3 torrents, and one of them has a low share ratio it would make sense to seed it more than the others.

Currently we don't support that

Are there any plans to make an alternate seeding priority method? or at least some additions to QM? Right now Ktorrent will download on torrents without peers or leeches, and will seed to torrents without peers. As well I'm sure there are requests such as this to add better queuing, or at least more intelligent methods.

There will be changes in the QM for the KDE 4 port, but we still need to discuss what changes exactly.

I also consider necessary a system of priorities (automatic and manual).
For example, I finish adding to several torrents new to one tracker. Initially, I am the unique seeder and the leechers download slowly, this is normal. But KTorrent (without clear criterion) stop upload very frequently, even being a great number of requests of this torrent.
