Thicker Terminal double bar line (& Repeat bar lines)

I have noticed that the thick side of Terminal bar line (end bar line) is too thin in comparison to proper specifications. The line should be three equal lines " ||| " with the right side coloured in. The current right side needs to be thicker " |[] ". I feel that the current terminal bar line resembles the standard double bar line " || ".

Great program!!!

Kindest regards.
