@iliazeus I mean the ones you swipe sideways. The way it currently works in most stock launchers is that you have the "home" page as the leftmost one, unlimited number of additional ones to the right of it, and some sort of stupid feed to the left (or nothing if you turned it off). It used to be such that you had usable pages on both sides of the home/default one. I want a modern launcher that does that.
@grishka oh, I get it now, thanks!
I use Nova Launcher (mostly out of habit, though it's a decent one). There, you can set any page as your "home" page, and then you can return to it if you press "Home" on any other page.
Nova is not open-source, though. But I don't know any others well enough to recommend any :)
