about QM3 Some suggestions

I'm trying to copy code from my code editor into a Word document while preserving the syntax highlighting, and I've run into two problems:

1.  `using` statements that span multiple lines in the editor are collapsed into a single line after pasting.
2.  Gray boxes appear in the indented parts of the code. Is it possible to remove them?
