Thanks for adding this for the user.

We have a tool like that here.  Should I add a link to this from the menu under "Tools"?

RC is already a feature on SportsCardsPro.  We show orange [RC] icon next to rookie cards in search results and browse by set pages.

Hall of Fame is not available at this time.  I'll let users vote for that.

> I've also seen a few listings that said the auction was ended because the item is no longer available.

eBay site is not always accurate with these.  If someone lists multiple copies and 1 sold but the other did not and the seller ended it, it could be listed as "ended as no longer available" but 1 copy did sell.

> seller has re-listed this item or another one like it

A buyer and seller did agree on a price at one point.  Yes we do not know if the transaction completed, but that isn't necessarily needed to determine the value.  If that sale was very high price and a rare item then we will often remove the sale because it was probably a fake bid.

> be nice to have a link to a cached copy of the listing page

Unfortunately ebay doesn't keep their pages around after 30 days.  It would technically be possible to cache the HTML or screenshot for every ebay listing but it would be quite expensive and take lots of development.  That would definitely be outside the scope of this request.

For collections you can already do an export to CSV, which can be opened in Excel or a text editor.  You access it via My Account > Settings > Export Collection.

We do not have a feature for wishlist export.

We've added backend support for this now.  Users can add whatever hardware and games they want.

We had these on the site for a while.  Never closed the request.
