Gridline Opacity

[jtharton]

When zooming in to certain levels the grid lines on bookmap show.  Here are is an example: https://imgur.com/a/GOZh2re

On the right you can see the gridlines and on the left if you zoom out one notch there's no gridlines.  I'd like a way to reduce the gridlines opacity or make them so that they just don't show up.  They provide a lot of visual distraction while trading at higher resolutions.  Support suggested I add the request to the new features requests forum.  

Thanks
