Re: [Scidvspc-devel] Patch2: MultiPV traffic lights for boards, inturn Enabled for Analysis Board

[C H. M. <han...@gm...>]

Hi,

This is an updated version of the MultiPV TrafficLights patch, which
transitions the colors from Green (towards 5) to yellow (1.5 to -1.5)
to Red (towards -5) in a relatively more smoother interconnected way
compared to the previous patch.

Have also attached a screenshot, which shows the newer coloring in
comparison to the prev logic.
