add function to highlight a group in cluster plots

[YeeLu]

Dear Dan,

I find your GUI absolutly handy and I am totally relying on it now. One thing that toubles me a bit is that when I have several clusters stucking close together I cannot really see which is which. TINT solves this by offering highlighting for each cluster so I am going though TINT everytime for double check. So I am wondering whether you think it is worth to add a cluster highlighting function to make it easier for checking cluster space of each cell.

Many thanks and best wishes,
Yi

This should be relatively easy to do, and I agree it's something worth having.

Note that there is currently a basic form of highlighting available: each time you click a group in the titlewall, that group is redrawn in the cluster plots, so that it ends up being "brought to the top" of the cluster space...but it's not as clear as it is in tint, I definitely agree.
