The mobile space has been getting better. For instance, Libadwaita will scale and collapse on smaller screens and all of the UI works with a touch screen.
It’s insane how good some libadwaita/GTK4 programs are at working well on large screens and small ones, and being able to switch between the two shockingly well at the drop of a hat.
Resize a window to a phone shape and many GTK4/Libadwaita apps, quite seamlessly, switch to a mobile UI that looks pretty well thought out.
I’m actually shocked the devs don’t make more of a song and dance about it, because they’ve done a stellar job and it’s currently overlooked by the community IMO.
