Previous to the latest update, 3 columns per row were an option.
I had my entire Microsoft Launcher set-up to maximize this feature. I found it clean and easy to use from one hand/thumb, with each icon easy to reach with one thumb, and an uncrowded layout.
There was also plenty of space to tap the "folder area" in Fullscreen Folder mode and "tap-out" of the folder with the padded space around the icons.
This let me use the Launcher in a more intuitive fashion when on the go. I also had less visual clutter to sift through while looking down at my phone while on the go or busy, and thumbing through multiple screens wasn't a chore.
Now that everything is condensed, I am finding the Interface annoying and MORE difficult to use.
I consider this a UX regression.
I would like the option in settings for 1, 2, 3, 4, or 5 columns
