StingingVelvet: Yep. I either "hide" them or sort them into a category called "trash" or something similar. It doesn't surprise me some have compulsive behaviors that make this not good enough though.
I hide them as well, but it bugs me that they still count towards the total number of games,
I also dislike several other features of the library, e.g. the duplicate entries for some games (Wasteland 2, Pathologic and System Shock all have two entries, one for the original, one for the remaster). This artificially inflates the number of games. Since gaming is a guilty pleasure for me which I'm somewhat ashamed of, I'd like the number of games I own not to be even higher than it actually is.
Yes, I know, those are fairly ridiculous problems, and of course there's no chance Gog will ever change anything, given how broken this site is.
