It probably is not. But personally I don't vote for it, since there are so many bugs going on here or other needed features, that are far more important to be fixed than adding additional things to the wishlist.[..]
You haven't voted because currently there are other issues?
That doesn't make sense, friend.
The wishlist is useful exactly to report all the problems that will need to be addressed in the future.
GOG themselves will, then, decide if they have the time to implement them.
EDIT: no wishlist link? O_o
GoG sadly merged by mistake my wish link with another completely unrelated wish, so i removed the link to avoid confusion....
