Issues

• I haven't experienced any issues.

• Although I consider the gaming experience equal to Windows there are
  remaining issues:

Sorry if this sounds stupid, but I don't know how to tell if a game is whitelisted or not. How would I do that? I don't like incidentally creating duplicate requests or requesting a game that's already whitelisted.

No repository file or test is named. Start by reviewing the Steam Play whitelist process and the linked runtime config options; done means determining whether Deathstate: Abyssal Edition is already whitelisted and documenting or handling the request without creating a duplicate.
