EDIT: As of the second version of One UI 6, they have changed the ... and words being chopped up issue, and instead replaced it with scrolling text. They've also changed the large icons to be normal size. As for the white background, they have changed it as well.
I suggest changing the white background on dark mode for the available buttons, Making application button icons the same size as system button icons, and to stop cutting up button names or just adding ... at the end.
