Just like Discogs where you can put into an inventory what you have (they name
it collection), it would be interesting to have such a feature.
It's basically a display without having to sell (i.e. right now you have
to be a seller to have an inventory).
I'm using currently wish list of the set I got at the moment and transfered
them into another wish list once I was done rebuilding it... I mean it works
but it's not exactly what wish lists are for!
