Passive tree searching needs better highlighting

When searching for specific things on the Passive tree, the highlighting option really sucks.

You barely go a glow on/off over like 2 seconds, and when searching for very specific things, its difficult to discern the actual highlighted nodes.

A suggestion I have is to apply a darkening layer over the non highlighted nodes, so the highlighted nodes stand out against the background better. I would also use a thicker effect, change color to bright YELLOW or GREEN and solid, not glow on/off
