Hello, dear Lutris people! 
I am using Lutris for about one year now, and I love it!
There’s just one thing that I miss:
As I have multiple Steam accounts (who hasn’t?) it would be great, if setting the account credentials for every Lutris-Launcher would be a thing.
I think it could be done without too much effort by creating an own Wine Prefix for every installed Wine-Steam game.
For pure Linux Steam it probably would be a bit more complicated. (Maybe some container standard, or using symlinks or an automated system for dynamic bind mounts?)
Thank you for attention!
