Issues

• Black background is inconsistent with the rest of the package:
• Links are sometime hidden, and colour can't be changed. I think this is the result of using a very light shade of gray + very thin lines

Proposed solution

• Suggestion to move to a more traditional white background / black font: move default to bg_fill = "white", font_col = "black"
• Make the edge colour a parameter (currently fixed to light gray : edge.color = "#adadad")

If we want to simplify choices, we can create two or three colour combinations and use as single parameter (e.g. style="default", style="night")
