UPDATED Mar 20
I've been experimenting with ways to recreate the Pixel experience and I've come up with a solid solution. This will require access to adb shell and does NOT require root. You will also receive OTA updates.
I asked HTC about updates on HTC 10 and they didnt answer.
Congrats on being a prick!
I've added the real display size of the Pixel 2 to the OP. Was previously using HTC's small but found the real equivalent can be set in developer options.
Set Display Size to Pixel 2 Equivalent
Go to Settings > Developer Options > Smallest width...
After 2.0 the extra spacing for devices with hardware navigation was removed. It looks much better at 2.0
Thanks for the update, your ROM has been the most reliable of the bunch and what I always fall back to. Great work.
