I switched from Nova to Total Launcher a while back and it’s been great. It has all the customization features I liked from Nova, plus additional useful features like folder swipe actions that Nova never had

Some newer headphones, like the Samsung Galaxy Buds 4 Pro that I just got, have 360 audio with head tracking. So, if you turn that on while you’re upright, then lay down, the audio should compensate for your movement.
