Actually, keeping the two lists at a distance can help (even if in reality it would be more useful to have some sort of indexing based on what I know of tags or categories) in some cases.
What most urged me was to have the notification on the side (the one that tells how much time is left until the auction expires etc ..) in common .. so even when one is watching the first team can see the bookmarks marked for the second team and the other way around.
