NES-001 is the standard Console.

An A-Z Picker
An A-Z picker (#, A, B, ... Z) at the top of the game lists would make it easier and quicker to jump down long lists of games. For example I would click on the “P” letter on the top and it would jump to the games starting with P.

You can already add consoles to collections. You click the "+Collection" button on the console like you would any other item. You can quickly find consoles for a particular system by filtering by genre for "Systems". It will show a list of consoles like this for NES.

Include an option for the 5 year price history on graphs (vs. 1 year or all time)
When you look at a graph of historic prices, you have the option of seeing prices for the calendar year, 1 year, or the entire recorded history. Yet most games started rising in value in the last 5 or 6 years, so it makes the graph hard to interpret. Can we get a 5-year option for the line graph?

create a wish list system
we need a wish list system just like the collection system but for games we want to get.

It would be nice to have a pricing guide for PlayChoice-10 games, as there's no firm price guide available online.
