Need help with Pibus and RPi3B+

[TooEasyL2P]

I have few questions. 



1. How to go back or use context menu on screen like this? I can set one of this actions on that navigation wheel when holding. But then I can't get context menu if I set it to back. 

2. Why visualizations doesn't work? I have installed Spectrum, I have selected in player settings, but it doesn't show up.

3. How that webasta thing works? Do I need to unlock car first to start RPi and then lock while holding? Or I can just hold lock button in the morning without unlocking car and RPi will boot up and start webasta? How long I need to hold?

4. How to fold mirrors? Before I had setting to fold on double click on lock. After update I have only "Programs". I don't know what it means and how to trgger mirror folding.
