Looks like 2022.12.3.2 improved the bottom bar:
- Heated seat controls can now be added (they fall into a space reserved for them, not among the 5 apps).
- Wipers, front defrost, rear defrost, and heated steering wheel controls are available (take up space among the 5 apps).
- 5 apps instead of 4.
- Replace the recent app space with space for more apps (or have that be a user option).
- Allow the app space to expand for more apps, reducing empty space on the bottom bar.
- Add headlight and fan speed controls to what can be put on the bottom bar.
- Energy display
- Headlights
- Wipers
- Heated seats
- Camera (useful for parking)
- Defrost
- Dash cam save clip
