Custom brightness level setting

[mmghv]

Feature request (nice to have) :

First of all, thank you for a great project.

Is it possible to have a custom brightness level setting instead of just a max level "High Brightness" setting?
I find myself needing to manually adjust the brightness every time I use the application, somehow it's darker than the other apps and "High Brightness" setting makes it way too bright for my eyes.

Thanks.
