Tesla software update version 2022.12.1 has just started rolling out with one of the most wanted features for Tesla owners. This update allows a Tesla owner to customize the bottom bar icons to their liking.
The Custom Bottom Bar Icons feature in the 2022.12.1 update is limited to Tesla vehicles with horizontal screens (Model 3/Y all generations, Model S/X from year 2021). Owners of vertical-screen Model S/Xs will have to wait for a separate update, otherwise this feature may not roll out to them at all.
This update also includes more features such as additional Tesla mobile app controls, child lock improvements, and an updated in-car web browser (see release notes below).

Additional mobile app controls
Mobile app improvements
Dog Mode and Camp Mode can now be activated from the Tesla app.
Note: This feature requires mobile app version 4.7.0.
Child lock can now be activated for only one rear door. Faucet Controls > Parental Lock, then select Right, Left, or Both.
Tesla hacker green and other Tesla owners have discovered that firmware update 2022.12.1 also has a browser update which is not mentioned in the release notes. According to Green, this update has tightened privacy loopholes. Users can also clear browsing data now.
Improved charging time estimation
Interestingly, Tesla included the battery temperature variable when calculating charging time. This results in a more accurate estimate of the time remaining to charge the battery on a Tesla Supercharger or third-party fast charger.
