Modernize preferences design
We need to get some mockups for how we might modernize the preferences dialog as Terminal moves to GTK 4. So lets get the design team to take a peek and see what their suggestions are.
I would just make one request, and that is to assume that all the preferences on the dialog are necessary, because I think they are. Contrast this with something like Console where you can probably get away with less options.
I did a super simple minimal port over a few hours, so everything is super trashy. But here is where I'm starting from. It is neither beautiful or coherent.
