If this option is enabled, when under an effect that prevents you from barswapping, FAB+ will switch to a single bar mode that only shows the active bar, after the effect ends, or the causative item is unequipped, the mode is automatically switched back to the previous layout. This has been tested and is working for Oakensoul, Volendrung, Werewolf, and the Lucent Citadel Wisp transformation (so it should work for all other similar effects).
