Hey glow muffin
Top right corner "options" "Theme" > try a few out and see what you like. I like "tomorrow".
I asked a friend to ask his friend about the host file issue.
This because his friend is a straight up computer wizard.
It was reported back to me that it does make you vulnerable to anyone in the middle.
Described as an open door to anything on your puter.
Then it was stated not to trip because the powers that be are already there regardless of opening that door.
