SVG hover style to tell apart arrows in a large component diagram?

+2 votes

Component diagrams quickly mess up when there are a lot of arrows. Would it be possible to add a hover style to highlight arrows with a different color when hovering over them? This would allow to see through the clutter a bit.

Something like this in the SVG defs element:

        <style type="text/css"><![CDATA[

          path:hover {
            stroke: #00FF00 !important;

YES! This is essential for busy digrams.

Ok, thanks for your suggestion.

In last beta https://dl.dropboxusercontent.com/u/13064071/plantuml.jar

We have added a new skinparameter. For example:

skinparam pathHoverColor green

The result is not perfect, but this is a good start!
