When will GOG finally implements this?

Any unofficial way to ignore them meanwhile?

It's been asked for years. If GOG wants to attractgamers from Steam they should implement basic functions rather than giving away games people already have on that platform.
The only way I have found, to remember that I am not interested in a game is to rate it one star. Maybe not fair but effective.

Bump

So any way?
I've heard that someone posted a method (browser script or smth) in light of recent Hitman 6 GOG drama but I can't find it.

This script, maybe?

And if you use this script to see GOG's titles in a grid/data sheet display, you can hide games you don't want to see there as well, although hiding them will only take effect where the script is used, and not in the whole store.
