Ability for buyers to mark an article as 'seen'

[rjasper]

Would it be possible to add a tickbox so that I can mark an item as 'seen'. And, on subsequent visits only show the 'not seen' entries (depending on my-profile settings).
As futher service a button "Mark all as 'seen' could be added.

That way I don't have to browse a hughe list of things I already looked at.

This would greatly enhance the use-ability for buyers.

I am collecting Dutch stamps and the listing is now 5,357 items. That's to much to browse every time.

I agree with this but it would have to cope with with auto reposts. The same problem arises with saved searches; you get the same items on the emails every time they are reposted - this is a real pain.
