I noticed you have regular cards and reverse holos, but there are cards that come in holo format and seems you do not have input on sales. Is this done on purpose? Shouldn't you include them as well? *Pokemon Cards 

This feature is useless and irritating

Hello! I am a new user of your app and have been collecting retro consoles for about 5 years now.
I have been slowly adding my collection and noticed that there doesn’t seem to be a section or items related to video game merchandise. I understand that “merchandise” is a general term. However, I believe that if the item is sought after, rare, and expensive, that it should have a spot on the app. Perhaps under a “miscellaneous” section.
For example I own multiple pipboys released by Bethesda to celebrate different game releases and the tv show release. These pipboys are very expensive, rare, sought after by fallout fans. The app does have the fallout 4 release version on the app. However I believe the other pipboys should have a spot as I consider them apart of my collection.
To further support my point, this idea could also help further simplify collections for users. the halo 3 pre order edition helmet is on the app, however it is only under the bundle itself. Some collectors only have the helmet itself and not any other items in the bundle. “Loose” is not enough to help classify this difference. A new section could help clarify this.
If there is such a section then I am sorry, but I would like to add my pipboys are part of my collection on this app.
Thank you for your time and I hope you consider this.

You should add a price guide for vintage/retro toys from the 80's and 90's 

These magazines should probably have a place on the site.

Please create a deal scanner on Cardmarket site where you could set a language and minimum card quality (like it is in their filters) for chosen cards.

Would like to see TY Beanie Babies added to the lists. Have ones that have certain generation hang tags, error and defects and also have the option without the hang tags.

An Android Version of the App.

Langauge variants of a particular card should be introduced into the marketplace. As the POP of some foreign cards from a set would be rarer, or harder to find. Not to mention cards exclusive to that country's set, might have different rarites of a that kind. So determining a card's set placement rather than language is very important, when it comes to rarity. Helping us gauge it's value. People are selling them, but their not prominent in the marketplace than English/Japanese pokemon cards.
