Thanks for sharing!
After a few minutes of testing (no gapps in addition, just a few of my favourite apps):
- ROM size increased from ~240 MB (debug version) to 300 MB.
- First boot after installation was surprisingly quick.
- Default size of icons and fonts is pretty small (can be adjusted to personal taste obviously)
- No crashes observed from neither default camera nor OpenCamera (took a few pictures)
- GPS indeed doesn't seem to work
- Sensors (CPU-Z): all seem to work, except AK8963C Orientation sensor (same as in CM ROMs).
(I guess that's the reason for missing 'Orientation' information in SatStat)
- Calls working (expected)
- Data and Wifi working.
- No root by default (that's not a flaw).
- Apps could be installed via adb, even if 'Unknown sources' were disabled (not sure whether that's expected)
- No significant battery drain during the night
- 'Reboot' is stuck on shutdown
- Working as secondary ROM in MultiRom
Looks quite promising to me, great work!

(missing GPS is still the killer though, before switching).
