brightjob4495 on stock OS, when you open that screen with all the apps you have active, there's an option to copy text from whatever you have on screen. Say I have an image of lunch menu open on my screen. I can just open up recent tasks and immediately copy whatever I want from. That menu. That's not an option on GrapheneOS as far as I can tell, even with Lens installed. I would have to save or screenshot the image and then manually upload in Lens to be able to copy text. I definitely miss that convenience from stock OS, especially since I work with a lot of documents in foreign languages.
If anyone knows how to bring back that function, I'd love to hear it.
