Add a way to track signatures, comic and sports. Use the persons signature as the base and then link it to a collectible. For example a Stan Lee signature varies greatly based off which comic he signed. Right now his signature caries about a multiple of x10 to the value of the comic. You can track the value of the signature based off the raw value of the of unsigned collectible 

Would like to see AGS Grading in the system. They are an up and coming grading service and would like this option to use. You currently only offer a BGS 10 and all other grades are whole number and does not include .5 ( 9.5) as an option.

Definitely need a place to track posters. Some are going for significant amounts and also affect cib prices. Snes chronotrigger is a great example. 

Inbox fills up fast with disc/cart only, etc. Really need a filter to only notify on CIB.

The filter option for region is completely gone and I have no way to set my filter settings to All regions or just a specific region anymore.

Dragon Ball (various) are sky rocketing in price, they should be added. 

The following game: https://www.pricecharting.com/game/famicom-disk-system/tantei-jinguuji-saburou-kiken-na-futari-kouhen has misspellings in the title and should be fixed.

The title should be the following: Tantei Jinguji Saburo: Kiken na Futari [Kōhen]
