Rated 4 out of 5 stars

works great; my client is pretty happy. it would be nice if there were an option to change the color/density of the 'thin blue line'.

This review is for a previous version of the add-on (1.3). 

Hello ndanieley - latest version of RWH add-on has controls of line color and density. Could you please try out and update your review with stars?

Cheers,
Jeeva
