If you are tired of managing wine prefixes, trying to get Proton to run outside of Steam, managing more than 1 Wine prefix, this is the tool to have. Saves you from doing everything manual and it a great help!
I was going to check the AUR votes, however for some reason it was removed.
This may be why:
My servers are currently down (a part of infrastructure has been restored fortunately) and I had to halt q4wine development until further notice.
AUR votes is 19 if it helps. I pulled that out of Pacman.
Russian invasion shut down his servers is the reason. Should be back after the war.
Won’t implement.
