Changes LGTM, gonna approve for testing but it is a 1600 line change so if another reviewer wants to take a look it to sanity check me it wouldn't hurt.

[Managor]

Installed on Stable and Main. The plugin runs.

A future suggestion would be to add a separate text field for environment variables inside game settings like requested in this issue ValveSoftware/steam-for-linux#11539

[Wurielle]

Decky Launch Options streamlines the process of adding launch options so adding %command% is optional, I recommend to add it just in case you want to mix environment variables + commands + args but if you're only adding an environment variable without %command% it will work just fine 🙂

Note: Thank you for testing! You might want to check out the testing guide and template for reviewers to accept your review as valid however 😅

Issues

Has the following major blocking issue(s):

• Clicking the "README" button opens an embedded browser that completely traps input. The B button does not go back, there is no close/X button, and the Steam and QAM (...) buttons stop responding. The only way to recover is to force-restart Steam.

Has the following minor non-blocking issue(s): None

Feature Suggestions

• The UX of having two separate settings pages (Decky QAM panel for global, per-game settings page for local) is confusing. Toggling a global option to local in the Decky panel moves it to the per-game page, which is not intuitive at first. Consider consolidating into a single settings page per game with the ability to set options as global or local in one place.

Summary

Installed from the testing store. Tested adding launch options to HL2 (windowed mode args) — the options appeared to apply correctly. Tested toggling between global and local options. Core functionality works. The README button browser trap is a significant usability issue that requires a force-restart to recover from.

@Wurielle Considering this PR blocked until the above major issue is addressed.

[beebls]

Just gonna need a comment from @Wurielle on if they want to fix that final issue there before we merge this

[Wurielle]

I need a little bit more time to investigate some issues that occured with SteamOS Beta but I don't think I'll be able to fix the orphaned menu entry issue, it requires to patch the menu after the plugin is already uninstalled. It can be fixed by restarting the device and doesn't cause a major issue. I do need to fix a crash occuring on the SteamOS Beta before this can be merged however.

[Wurielle]

@beebls I had to fix a few breaking changes introduced on the recent Steam Client Beta. Sorry for causing a re-review..

Summary

I looked through the PR details and focused on its content, and tested changes.

Aside from the issues I didn’t test, everything looks good to go.

[Wurielle]

Thank you for the review!

In order to add launch options in a dropdown they must have the same Value ID and different Value Name, those fields are available under the "Advanced" button. Here's the relevant section from the README as reference:
