The app would be as customisable as needed if swipe direction weren't locked to "down". I already use the Android swipe gestures for the navigation bar (used to use AIO gestures in Android k-n) to get more screen space and consistent positioning(hiding buttons shifts the screen and ruins muscle memory), when I try using the trigger on the bottom it uses up too much space or is too thin to reliably bypass the nav controls.
I tried the side triggers, but they're both uncomfortable because habits say to swipe down for settings, or swipe into the screen for edge triggers.
The swipe that's needed is also very long and requires a break to trigger the 2nd layer.
Please add at least 1 of these 2 related settings.
