I really like the new integrated git change tracking, but I’m wondering if there’s any way to configure this feature to make it more eye-catching. Can I set added lines to have a green background, for instance?\

No, but you can make the line wider using the line_diff_width key in your color scheme. Refer to the docs for details.
There may also be a third-party package that provides this feature, but I don’t remember any. GitGutter only affects the gutter iirc.
