Great feedback.  I plan to add something like this sometime this month.  Sorry it isn't there right now.

Thanks for suggestion.  That is not an option at this point.  I'll wait to see how popular this is before implementing it but it should be doable.

Beautiful.  Glad that provided what you needed.  

Yeah, I will consider that vs all gaming memorabilia.  I'll keep an eye on how popular this request is to decide how to prioritize. 

Thanks for the feedback.  Are there particular features on a native app that aren't available on our web app?

The development costs and maintenance are much higher on a native app than web app.  I definitely want to know if there are particular features that won't work with web app though.

Thanks for this suggestion.  We consider these "game memorabilia" if they didn't come with a game.  I'll wait and see how popular this idea is before considering it, but that is the reason we don't have those on the site at this point.  We don't track gaming memorabilia.

Someone added this to the site yesterday.

I've wanted to do something like that for a while but never made it a priority.  You can now change your privacy setting for your collection on the /settings page.  You toggle on or off "private".

If the collection is private only the owner can view that collection.  Other users will be redirected to the home page as if that page didn't exist.

I've uploaded all of those cartridges to the Mark III page.  They will appear in about 24 hours (after server cache resets).  Thank you
