Thanks for that feedback. That is a feature we want to add in the next update. I don't have an exact time frame for it, but it is the highest one on our list to add. Stay tuned.
Sounds great. Thanks for any contributions you can make in the future. Good luck with school (I assume based on your schedule)
Can you show me a screenshot of what you are seeing? I definitely want to fix this but I need to see the page you are looking at to fix it. Thank you
These should all be grouped together already.

I see card data in all of the Johto Champions sets. Please check again.
I've uploaded the set and card lists for the Advanced and Advanced Challenge sets. Those will appear on the site after 24 hours.
If you have any desire to add photos to these sets, I can grant you contributor privileges on the site. Please email me your account email address to sales@vgpc.com
Thank you for all your help with this topic.
I've corrected that problem with Die Cut 1999 Movie cards. Correct ones have been added and other Evolution cards moved. Because those cards have a different number system, we consider them a subset so they will be in a different set than the other 1999 Movie cards that go from 1-59.
It looks like my upload for Johto Champions didn't work quite right the first time. I've added them now. They will show up in 24 hours.
We will grab images as we find sales data, or users can add images too:
We'd love to add these. Do you know of any lists of these cards? We can add them to the site.
We moved all of the subsets to their own card lists. For example:
https://www.pricecharting.com/console/pokemon-1999-topps-movie-die-cut
For Johto, we've added all of those now too. You can see all of those sets on the site using the "Find Set Tool"

I appreciate your feedback. I can understand your points.
Like you said in a previous comment, people can't identify the card set based off of the card alone. We are using the copyright date for the sets (not the release date because that isn't printed on the cards or the packs for that matter).
Most people who use our site use the search feature and they would search "Pikachu Topps TV" and maybe the card number and find their card on the site. Then they will look at the picture and see that it matches their card.
We are going to stick with the names we have on the site because it works for our users and matches the other card categories that use the same set naming convention.
I appreciate your info on this because it did help us improve the data we do have (and add some missing cards).

Thanks for this input. An "add another" option under "in collection" would probably work well. Sort of like the drop down we have for "+Collection".
I've made a note about this and hopefully we can add something like that in the future.
