long story short, many devices have different system fonts and some even have the ability to set a custom font for the whole UI.
so, instead of having to select a font for any text items which then gets forcibly applied to it, an option should be made to not set a custom font but to use the system's setup. in fact that probably should be the default in my opinion.
