An honest feedback on OOS 3.5 community build for oneplus 3. If you're confused to flash or not flash, then this feedback may help you.

MISSING STUFFS:

1. number of quick toggles reduced to only 9, please add another line (we have a big screen, you know?)

4. missing total black theme and missing accent color customization
5. daydream mode for clock app is showing both analog and digital clock
6. missing led light customizations: those was really great!
7. clock app is missing incremental audio for alerts
8. Android pay not working (already warned in the release note)
9. Battery Percentage in status bar is incorrect (already warned in release note to not use system UI tuner)

NEW STUFFS
1. System UI is fluid and N-ified. Performance is top notch.
2.Bunch of new animations
3. There's a switch to lock the hardware buttons
4. Dropdown menu is different and has some toggles immediately after you pull it down
5.There's a new weather app with some cute animations
6.New graphics for the clock app
7.New shelf with different Graphics Can resize widgets in Shelf
