About the UI I become "they" but installing the GNOME extensions that I need to make my desktop look like 99% of what I would it to look and behave. It takes a few minutes to get to 80%, a few hours to get to 95% and days (a few minutes here and there) to 99%. Those huge menus and tabs on GNOME terminal eventually became skinny with a good deal of CSS and AI.
Do most people want to get through that research? Absolutely no, I don't expect many people to follow me into that rabbit hole. They can get the default or Windows or a Mac, no problem with that.
But with AI, "go through with that research" is tell Claude code how you want things to behave, and it'll make it happen for you.
