sdkconfig: - increase encoder dead-time to fix bug where encoder triggered multiple short pressed events at one press. E.g. instantly submitted value when entering a menu page sometimes button: - decrease input-timeout (long press time) to 500ms same as encoder long-press - empty encoder queue when changing to MENU - re-enable or increase joystick scaling to have more resolution at slower speeds
