Option to blur or remove thumbnails in recent apps screen

[DSDV]

Hi,
i really love your app since it brings me one of the most loved MIUI features to LinageOS / Lawnchair.
But for example if i want to protect my gallery but everyone can see the preview thumbnail thats a big flaw for me.
LinageOS 17.1 with Magisk - would happily donate for this feature ;)

with kind regards
