I've been receiving a couple of feedbacks and requests of default playback order. Namely, current Remedie displays the feed items as it appears in the feed initially (when you first subscribe to the feed), and then new item will appear on top of the existent items.
This is something you'd expect for most feed readers, but it might be not so useful when you want to do continuous playback on something like Nico Nico Douga mylist, where they have all episodes from the latest to oldest. There's a hack to specify the sort order in the RSS feed for nicovideo.jp and a patch to change the behavior globally (not recommended unless you know what you're doing), but fundamentally this should be fixed on Remedie UI side, so that you can toggle the sort order by clicking tabs. Or even random playback mode to enhance the jukebox-like experience.
I plan to add the ability to sort channel items in-place by mangling URls, like localhost:10010/#channel/5?sort=date&order=asc or something similar in the coming 0.6.x release.
UPDATE: This is now implemented in 0.6.18.
