Can you make the visible/bigger (too small) the AUX (12V) battery ?
AUX (12V) battery information is most important to me

This request is not so simple as that part of the system is made up of many graphical layers overlayed on each other and having to be adjusted for different screen sizes and orientation. It is certainly possible to make bigger. The fastest way would be for you, or a developer, to make the change and submit as a Pull Request in github.
