Native Samsung Launcher (One UI 3.1) has gotten so much better over the years. It's increasingly clean and snappy. But I often find myself using Action Launcher, Nova, or recently, even Niagara (which is different, but kind of cool).
The ONE THING that always makes me drift from One UI is the inability to make COVERS for the folders on my Homescreen. Most of the others (Nova, etc) have a swipe gesture to "access" the apps within the folder, but tap to touch the one as a cover. It's SO nice and makes the Homescreen clean, organized, helpful.
Just saying... I'd love that if it were a feature... Even if only in good lock or something!
