When importing, there will always be a failure. I am reimporting all my games (2000+) so some systems have a couple dozen failures because of names or misspelling.  

It would be nice if when it finishes and gives you the list of failed items that it would return that list as links using the name as a search, and just for the system if used.  

I am in the process of organizing my card collections while also continuing to add to it. This has created numerous instances of identical listings in my collection for the same card. Let’s say for instance I scan in 5 bulbasaur cards. I scan one of them, set the quantity to 5, and add it to the collection. Later after opening a pack, I get a new, identical bulbasaur. Once I scan it in and add it to the collection, I’ll have 2 listings for that bulbasaur. One listing would show a quantity of 5, and the 2nd listing would show a quantity of 1. Since i use the default setting for condition and i verify the set before adding the cards to my collection, they are identical listings that are separated due to the time they were added. 

I would like a feature that allows cards with the same values (i.e. condition, set, etc) in my collection to be automatically condensed. I would rather see a single listing for a card with the correct quantity rather than a bunch of individual listings from each time I’ve added that same card to my collection.

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.

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.
