[Qgis-user] raster map legend

[Matthew Landis]

John - thanks for the clarification.  It's too bad this is not possible, 
as this seems like one of the biggest limitations of QGIS for using 
rasters.  I often find it important to know the actual numbers I'm 
looking at on the map, and not just the relative values.  Without a 
legend, it's impossible to know this. 

Does anyone know of impending plans to implement such a thing?
