Battle.net desktop app

For years, monitors are getting bigger… and bigger… and bigger. But i’m still wondering, why battle.net app (or any other gaming software like steam etc) don’t have: increase UI scale / font size?

I cant be only one who owns 32’’ monitor or bigger? And i don’t wanna keep my distance about 20cm from my nose to monitor, to read these tiny texts.

Like web browsers i just can shift+scroll either zoom in or out if needed. Or like in WoW, i can customize my UI scale and font size. But why not in apps? My eyesight isn’t like it used to be when i was 15, but its not getting any better.
