Whenever I am drilling down into some of my filters, it become increasingly difficult to quantify how many items and how much they are valued in the filter view.

For example, I might have 100 items in a folder with multiple different categories from pokemon to football and video games. Whenever I select the pokemon filter to just look at the pokemon cards in that folder, the value and count does not change, even though the filter took effect. So it still shows the value and count as the same in the entire folder, but does not drop down to the actual count of just pokemon cards and just the value of those pokemon cards. Would be helpful for doing quick math on lots and seeing how many i have after shows where ive traded off certain items. 

In https://pricecharting.userecho.com/communities/1/topics/722-show-the-game-value-in-the-wishlist the Wishlist has been extended with functionality to show prices. Currently you will always see the loose price, but for higher priced items that could differ A LOT from the actual CIB or even sealed price. I use the Wishlist a lot at conventions to quickly check games I want and what their prices are. Needing to switch to every game isn't user friendly at that time (with slow connections).

It would be nice to either choose the different condition per item (like suggested in the above url aswell), or (if its easier - a less extensive feature) make it customisable for the entire Wishlist to either show prices for loose, cib or sealed.

I would like to see the popularity of different items in a set (for example, how many other collections an item is present in) and to be able to sort items by popularity.

Add Star Trek Cards to the site

When looking in my wish list for cards I may want to purchase, It would save a click if there was a "buy" button next to each entry instead of clicking the card's page and then clicking the buy/sell button

Every item seems to be stuck at the last 30 sales.  The should be a way to look at the full history.

Would like the option to include Tag in the "what grade" and or "grading company selection" 

Japanese versions should be added to pricing

Can you please add the Union Arena card game by Bandai? Union Arena has been out in the United States for over a year and continues to gain traction and popularity among played card games. Each set is focused on a popular IP such as Bleach and Jujutsu Kaisen. 
The card game also draws a lot of popularity between card collectors. The alternate art or chase cards often maintain high value, similar to Dragon Ball and One Piece.
