* Add Auto Lock Time setting * Update .gitignore * Add value_index toolbox module * Auto locking basic implementation * Better AutoLock implementation, edge cases and cleanup * Fix NULL pointer crash * Turn off backlight shortly in locked mode * Re-enable auto lock after pin lock * Correctly handle start when pin locked * Use timer to hide locked hint * Use a single state variable instead of multiple bools * Do not call update callback recursively * Allow input when the Unlocked hint is shown * Add a delay to backlight switch off while locking * Better user input handling * Switch backlight off after pin timeout * Correct grammar in notification settings Co-authored-by: あく <alleteam@gmail.com>
