That definitely makes sense.  I'll make a note about this and see how popular it is with other users.  I think I know how we can implement it on the backend.

We make our website mobile friendly.  You should try browsing it directly on your phone and see what you think.  All the latest features and updates happen on the website.

You can even save the site to your phone’s home page so it looks and runs like a regular app. http://www.howtogeek.com/196087/how-to-add-websites-to-the-home-screen-on-any-smartphone-or-tablet/

Most of our website users are on mobile phones now.

This requires updating just the one thing (website) and all users get the updates, instead of updating three things (website, ios, and android).

Are there particular features that we can't offer in a web app that we could offer in a native app?

We do track listings/sales from the UK for our PAL game lists.  PAL NES, PAL SNES, PAL PS2, etc.  Example:

PAL Mario 3 search

For each of those games we will show completed sales from the UK and the rest of Europe.

Was there a particular integration that you wanted to see with eBay UK?

Joseph.  We don't have a simple link to click to convert a collection into an item for sale, but I think that would be a great idea for us to add.  I'll add it to my list of feature requests.

You should be able to export your collection and then use Excel and our bulk publishing tool to list them all for sale with minimal changes.  You would export, then add a little info to the file to make it work for selling (like the selling price) and then you would upload it for sale.  

I hope that helps for now.

This is live on the site:

This is live on the site as of 2017.  You can choose your currency in the upper right corner of every page and that currency selection goes with you navigate the site.

The sort order default changes per user so every future visit will be sorted by your preference.  You just need to make an account so that sort order default is stored for you.

I'll make a note about changing this in the future, but our tests showed that most users prefer popularity instead.

You can sell your Nintendo NES Console here:

NES-001 is the standard Console.

You can already add consoles to collections.  You click the "+Collection" button on the console like you would any other item.  You can quickly find consoles for a particular system by filtering by genre for "Systems".  It will show a list of consoles like this for NES.
