@andycarolan @ashortbusvet @vkc I'm sure a few design & UI tweaks could help in some apps, yes.
But I tried the rebuilt desktop matrix client Fractal (on Gnome, on Linux) last week. They haven't implemented a way to change font size yet (that I can see), and the type is too small for me to read comfortably.
It's not unreasonably small. Probably about the same as mastodon on my phone -- but I have my specs off and the phone 20cm from my face, can't do that with a 27inch monitor =D
