This plugin for Deluge pauses (and resumes) auto-managed torrents according to an hourly schedule.
This means that if you don't want the preset schedule to affect a particular torrent, you simply change the auto-managed setting on that torrent to false.
There is also an option to ignore any torrents that are seeding only; this is useful if uploading is not counted towards your quota.
It can only be configured via the web interface (or by hand); there is no GTK UI for this plugin.
If there are any issues, feel free to drop me an email at email@example.com, or better yet, fork, fix, and I'll pull your changes.
