I use the lot value calculator daily for buying/selling/trading. It would be super useful to have each list be saved with it's own id in the url, just like the automator does.

Right now, I have to print/screenshot a list before composing a new one which is not ideal.

Some buyers don't read the description and then leave negative feedback because they didn't get what they expected. They also email and act like a smart ass and try to make an argument, then two days later, they purchase something else. Then I have to cancel, giving them the opportunity to leave negative feedback once again.

I would like to have the Game Wave Console add to the site.

With the addition of the sports cards "systems", it is now an annoyance to have to scroll down past all of the 20th century sports cards categories (like 1972 Topps, 1994 Fleer, etc), this takes up about half of the list of systems when I'm scrolling through the systems in my collection, even though I don't have anything for that system in the collection.

Please filter the collection's systems list to systems only in collection.

Add ability to batch add games in bulk to your collection by scanning the box barcode. 

Add Xavix Port console and games price tracking please :) 

Have one umbrella category for most of the gen one consoles, such as the coleco Telstar, Atari Pong, Magnavox consoles, Wonder wizard, and tons of other plug and play type consoles.

It's relatively trustworthy and I got games through Mercari for a price

Would it be possible to add the Colco Telstar systems as a tab Under other
