I’ve tried looking for launchers that have this feature, but have yet to see it mentioned anywhere.
I despise how the focus of development for at least the past decade has been form over function. I like information-dense displays, and Google has gotten everybody to waste so much screen real estate on looks (never mind other crappy UI decisions). My home screen widget layout is the one big thing keeping me on Nova.
I think one of the main selling features that made Octopi stand out from the others was the multiple home screen layouts. I agree with you and would prefer only one, but supposedly it’s a killer feature for people who have folding phones with multiple screens so they can have different layouts for each mode the phone is used in. Hopefully a toggle will be made for us normies somewhere down the road to just have one. Or, maybe I’m being closed minded and there’s another way I could be using s landscape homescreen that I haven’t thought of yet.
