Increase Icon Size / Text Size

[breitgo]

• Currently doing my first steps with NSPanel and wonder if there is a way to modify it a bit for visually impaired. E.g. I would like to increase the icon size which gets me from the home page to TRV controls. 32px is a bit small here.

• Same for text for hardware button 1&2. Here also the question if I can modify "push & hold" to get me to e.g. the climate page.

• How to remove / replace the background image?
