I’d like to work on this issue because I work across both frontend extension development and security-focused state management in wallet-style applications.

I’m comfortable working with React-based settings screens, persistence layers, and event-driven logic like inactivity detectors, and I understand how important auto-lock behavior is for protecting user sessions in extension environments.

This issue fits well because it combines UI configuration, state persistence, and secure timeout handling, which are all areas I’ve been actively working with in both frontend and security-sensitive application flows.
