Save User Profile Preferences for line color, gcp color and size, etc...

Why is there no way to save the preferences that I prefer? I hate the blue/green gcps. Too hard to see. I prefer pink. And I like them to be larger. Why can’t I save that to the default?

It would also be great to save preferred background color, system resource preferences (In custom template), and whether or not the sky toggled on/off.
