CGC grades go in increments of 0.5 up to 10, then have Pristine 10 and Perfect 10. Pristine 10 is tracked but Perfect 10 is not.

Let me delete all the items in a particular folder with a streamlined way to do it quickly

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.

I see we now have the option to add Ebay sales. Would it be possible to add Heritage Auction sales as well? There are a few items that weren't added until after the sales happened, and they're rare enough that no sales have been registered since. 

For silver and gold coins, it would be nice to have a running total of how many ounces of silver and gold you have in total for the entire collection

Could we add card condition for accurate prices on damaged, Light played, heavy plate,d and mint cards?

They are some quality cards and have great artwork.
