Idk if this counts as i dont really involve myself in a lot of discussion, but MAN do i miss two button navigation. it may still be present in some other Android distros but on Graphene an update removed it for me a while ago.
It felt easier for me to reach on my gigantic phone lol, and i enjoyed having a home button that i can just tap vs. A gesture bar that requires more motion to operate. I also appreciate that tapping to go home, swiping up for recents was more distinct than swiping up to go home, and swiping and then holding to access recents. Its definitely something i can live without, and i expected it to die, but a part of me was just hoping that my little pill button would live on forever
