I see that I cannot add labels myself, so I added info about this being a feature request to the title.
Hello @KennethNielsen, please go to Steam -> Settings -> View Account Details -> Preferences -> Platform Preferences and select the OSes that interest you. After that, does browsing the storefront behave as expected for you?
Closing as this should have been implemented some time ago.
Nothing extracted yet.
The browse by category function (which I would otherwise very much like to use) is not very helpful when using a minority platform like Linux, because it will show a bunch a results that I cannot play.
It would be nice, if it was possibly to browse by both parameters.
If that is possible by some other means I apologize for the noise.
