First post, so I hope this is worthy!
Anyway, you know how there is the option to add a peer to the list, and how when you resume downloading, that the trackers will need to resource all of the peers, how about, in the torrent properties screen, you can go to advanced tab and click "dump to peers to .bcpl (bitcomet peers list) file", which will be automatically reloaded when the torrent resumes.
When the download continues, bitcomet will search for these peers as they were last seen providing a seed, if they are not up however, they will be removed, and when this process is completed, the trackers will start doing their thing, updating and searching for newly available peers.
Why would this be useful: It will provide a list of peers that some or even most will be up, ready and are reliable sources/seeds/peers.
What you may think or say (all of which are possible?):
Trackers already do this
it may prove to large
it invades the privacy of a seeder
may cause problems for trackers when it has to compare between the list and online available seeds
may cause compatibility issues with peers that are now dead but were alive on the list
may interfere with the downloading process
may lengthen the times it takes to start the download
Those are guess work, but I hope this idea comes to light, and appears in the next update.
But either way, you provide the best torrent down-loader I've seen, and you do a bang-smash job and maintaining, upgrading and providing it with features. I love you for it!
Keep up the good work!
