Improvement for legend symbols ?

[Marc Monnerat]

Hello,

Ah geological maps! I've solved this problem using many layers and
organising them into a hierarchical tree menu (one pro age, unit, etc.)
turning them on/off. But having 500+ classes is still a big trouble.

In general it's nothing to speak of, but geological maps often have plenty of classes in a layer (the one I'm working on has 182) and a legend containing all of them would be really huge. It is my intention to have the legend only show the classes resp. legend items currently visible inside the actual map extend but I found no way to manage it without MapScript. Only at one place I found a hint to that feature: Bug # 750. I can imagine the needs for such MapServer feature is growing. Does anyone have an idea if this will be implemented in the near future ?
