Hey - I'm a newbie at this and wondered if someone could clear this up for me. What is the deal with the Favourites/Shortlist?

I can only add a tiny amount of players on there and I can't remove ones I'm no longer interested in if I've bid on them (especially after I've lost the auction etc.). It seems like the feature is a little bit pointless in it's current form. It can't really be used as a scounting tool and if you've lost a couple of auctions you can't free up space to add any more until the next day and they all disappear!?
