Higher contrast dark background (not the slight off grey) for setting, timer, health app etc... (like the files app)
Downloads quickaccess button like in 1 ui 8 in files app
Higher contrast colors on widgets (that still follow color theme) for samsung widgets such as device care widget
Auto close recents menu when all are manually closed just like when the "close all" button is pressed
More uniform aplication of high contrast, saturated colors and new gradients accross the whole os
Move checked checkbook in samsung notes app to a section at the bottom of "checked boxes" and allow to delete all of them at once or uncheck them like google keep notes
I like the new gradients and the search boxes in the apps, settings and other app menus
