icon to reveal the “Quick Settings” sidebar.
When turning on Frameless Mode, you will no longer see the Quick Settings button because there’s no frame. The only way to exit Frameless Mode is by swiping in to open the Quick Settings sidebar.
If Swipe Gestures are also disabled in Hermit, then you won’t be able to access any Hermit features at all, so Frameless Mode is automatically disabled if you have Swipe Gestures turned off.
