If you keep your Pixel plugged in for a few days, it will give you an option to limit charging to 80%. There’s no other way to activate it currently, but that should change soon (the Adaptive Charging option will have three options instead of just on/off).
OK, so the current dev implementation seems to make accessing notifications one-handed nearly impossible? You need to reach somewhere to the left half of the upper edge to pull them down - the top right corner is already far enough from my thumb most of the time to be a bit inconvenient to pull down on.
And I hope they bring back some quick toggles to the notification screen, it would be awful to have to go to the full quick settings menu just to turn on the flashlight, lol.
