Zoom In & Zoom Out problem!

Hello Dear Support!

 When i start "Cacher" i use "Zoom In" because this helps me to better see my code. But i have a problem when i exit from program! 

 When I run the program, the font is again the one that is installed by default. That is, it is again small.

 How to use Zoom In that I need and that it was always bigger?

 I want to use bigger Zoom In by Default.
