It’s really not that hard and there are plenty of guides available. If you are unable to visit the “store” (discovery), download a program and finally run it, then maybe you should just keep using Steam and not complicate things.
I feel like if you are smart enough to know that Heroic Launcher exists then you could figure out how to do a google search on how to install it. It’s not like Windows “just works” every time
No I just think you’re exaggerating the problem and had a bad take on it. In my opinion Steam is harder to install on Windows than Heroic Launcher is to install on SteamOS.
Messing with Proton isn’t required and I am sure most games will figure out how to add a shortcut to Steam.
