As tested on a Pixel 2 (but mods were applied in a universal manner):

* Enable Astro mode for Pixel 1 & 2
* Enable Focus options in Night Sight (along with "infinity" - may be same as far)
* Modded lib for Learned Depth in Portrait Mode (Pixel 2)
* Enable Super Res Zoom while zoomed or in Night Sight (no zoom required) - this is like Pixel 3 stock
* Enable auto timer (photobooth), it's in the selfie camera in the Timer options
* Enable synthetic fill flash for Pixel 2 and enable SFF in Camera mode for 3a

More advanced options/features to come later, please don't ask about them...For now it's a quick mod for those who want an "upgraded stock"-like app for their Pixel 1 or 2.
