Its not as easy as launching from steam

Nonsense! Often adding as a non-steam game and using proton is one of the fastest ways to get up and running!

But yeah, it’s trivial

Proton does. I switched from Mullvad for that very reason.

Won’t speak to Webstorm, but hard disagree when it comes to Rider. VSCode/Zed really fit into an entirely different category from Jetbrains IDE’s. Lightweight editors vs full fat development environments. There are use cases for each.

Do you have any sources for this?
