How to customise directions path rendering in OsmAnd? OsmAnd+ 2.3.5

Is there a way of modifying the look of the directions path? There is too much going on there to my liking so I would like to:


remove the yellow arrows (not sure what they signify but they obscure the road names)
remove the black arrows (they are less intrusive but still obscure road names)
change the colour and transparency of the purple path
It still remains a mystery to me where the black arrows are hiding but I found a way to address the two other requirements.

First I went through a renderers primer which prepared me nicely for the task at hand. Once completed the solution turned out to be quite simple, albeit a bit hackish. I also made the fat purple route a little slimmer. For completeness, here is the entire renderer consisting mostly of my comments:

&lt;?xml version="1.0" encoding="utf-8"?&gt;

&lt;renderingStyle name="Decluttered directions path" 
    depends="default" defaultColor="#ffffff" version="1"&gt;

    &lt;renderingAttribute name="route"&gt;
        &lt;!-- for some details on 'whatever_DIGIT' named attributes see: --&gt;

            route described by:         color and width
            skinny arrows described by: color_3 and width_3
            black arrows described by:  ?
        --&gt;
        &lt;!-- first two hex digits of a colour specify opacity: 48 ~= 30 % --&gt;
        &lt;!-- disabling skinny arrows by setting opacity to 0 --&gt;
        &lt;case color="#4800cd0a" strokeWidth="10:8" 
            color_3="#00ffde5b" strokeWidth_3="7:6"/&gt;
        &lt;!-- set it up in a similar fashion for the night mode:
        &lt;case nightMode="true" color=.../&gt;
        --&gt;
    &lt;/renderingAttribute&gt;

&lt;/renderingStyle&gt;
