Allow to bulk edit things in the collection, having to check things for every game gets tiresome with a big collection.

Also allow to easily change a game version from NTSC to PAL or JAP, since when I imported my collection it was added as NTSC even tough most of them are PAL.

PS3 and PS4 are region free.  

Add coverage for Japanese PS2 games. 

It's cool that these games are included, but they often clog search results and they're almost never what I'm looking for. For example, if you search "Mario GBA" you get 29 results, 10 of which are Not For Resale titles. That's over 1/3!  Maybe give the option to filter them like is currently done with region. A little option that says "Include Not For Resale Titles" and let people pick. 

i have a bunch of these and this would be really cool because its a part of video game history

Just started a collection of Nintendo power and would like to be able to mark with or without poster. 

Exports are always in USD.  Let users export prices in their preferred currency

Can we add variants? Some of the Xbox Platinum Hits are very rare, such as 50 Cent: Bulletproof and command a higher price than the black label version. It also helps with the collection side of things to see what variants I need.
