[BioC] Fine tuning heatmap.2 graphics

heatmap.2 can show a color key (use key=True) and density information 
histograms.

The color key is probably not so important if you are letting the 
heatmap function scale your data - see also option scale="none"

No, but its a question I had been wondering about too.
