This thing is really slick! I haven't played around with it fully yet but I have yet to find something that this thing doesn't do that Downcast does and that's saying a LOT.
You can sort feeds by oldest/newest first by changing the play order for all feeds (In the DC Menu>Settings>Global Feed Options) or on individual feeds by long pressing on each feed> Press Feed Options>scroll to Play Order.
You can leave the play order at the default setting and create "User or Dynamic" playlists that will back feeds anyway you want.
