Old Oreo Recents Panel workaround

[Fullmetal Jun]

U must not use Gestures navigation. Use buttons. U should also use a custom launcher.
Freeze/Disable Samsung Experience Home using Titanium backup or whatever app to disable it.
Recents will become like pre-One ui although a bit uglier since it looks zoomed-in.
To go back, close any apps in the Recents menu & enable Samsung Experience Home.
