This is the first-ever release of this tool.
It has only basic functionalities and there is a lot of room for improvements, visually as well.
Have a few bugs that I could notice like when you log in for the first time, it will update your game list but won't reload the app so you will need to close and open the app again.
Also, it will use your default wine installation and prefix (~/.wine), so some games won't work if you do not have basic dependencies there like vcrun, dotnet, dxvk, etc.
