Why not use transmission headless with the web interface? ( Ok, Transmission's web interface is a bit shit and you have to use the command line for some options.)
Defaults to bright mode. Well, I say defaults - is there a dark mode? Why don't all sites support a switch, defaulting to dark in case you don't want to blind yourself?
Imagine an app without keyboard shortcuts. Web sites.. sorry,apps, not having them is one of the reasons they suck. Please, try and compensate for sucky sites by pretending better that they are apps.
I am sincere. You've picked some pretty obvious differences. I'm talking about the vast majority of fonts which are to all intents and purposes identical. I don't know if you have a kindle but to restate my original question - if you read the same book using each of the 8 or so built-in fonts, do you seriously believe you are reading 8 different books? I'm sorry, it's just a nonsense. Sure, you can have a favourite font or dislike how..i dunno..descending letters look, but I simply don't believe normal human beings look at a (normal, not comic-sans etc) font and a) give a shit about it, and 2) feel that one is more "professional" or "zippy" or some other adjective, like a designer has reached into their soul.
It's bizarre isn't it? To read the sort of horse shit people write about fonts you'd think the same text in different fonts conveys different meaning. Maybe this is just yet more wrong -by-design AI output?
