Any library devs that can help me on this?

You can disable/enable inspections in the settings, or even create custom profiles

@Czar Yep, but it disables it for all projects and all modules anyway. I'd like it to be applied on a per-module basis where the sample app would get the warnings, but not library module

Settings → Appearance & Behaviour → Scopes Define your modules' scope Disable inspection on this scope.

Thanks a lot @Czar! Still had to invalidate caches and restart, but that solved my problem! :😄

Write tests for every public method, they will no longer be marked as unused or possibly private.

Nice idea @czyzby !
