The ability to hide owned games during sales or in searches would be very handy for those of us who already own many of them.

On sales like this one, I regularly find myself browsing through the Thinking tab only to find I already own over 80-90% of the games and it's quite a tiresome exercise to try and spot the few which I don't yet have.

Seeing how there are wishlist entries for such a filter dating back 5 years, GOG obviously isn't in a hurry to implement this feature so I decided to make some browser styles for the Stylus/Stylish extensions for Chrome and Firefox, which let people hide owned games on sales lists, searches, browse games lists, etc.

This one hides owned games completely so they don't even show up:
Hide Owned GOG (No Display)

The other one just darkens owned games so they still show up but are barely visible:
Hide Owned GOG (Darken)

If anyone wants to try them, just grab the Stylus extension for Chrome ( here ) or Firefox ( here ) and once installed, visit the aforementioned userstyles pages, click Install Style and enjoy future sales and browsing without owned games crowding up your view.
