And here is how it looks, if you open an already configured single banded
layer (I've also added the data type information, it can be quite useful to
understand rendering issues):

See that "reload band definitions" button? It forces GS to go down into the
reader and fetch the band informations again.
In case of newly configured layers, the data type will show up
automatically.
Here is a rain layer, reloaded and with the unit of measure manually filled
in:

And here is a RGB layer instead, sporting the default uom for rgb bands,
which is the radiance unit of measure in SI
terms (http://en.wikipedia.org/wiki/Radiance):

Now... looking at the GUI one would be very tempted to make the band name
and null values editable... which is doable,
but not immediate, we'd have to wrap the readers and getting out of
resource pool so that the reader returns
GridCoverage objects that have the desired metadata. It's doable, not
extremely hard, but I'll leave that for another day ;-)
Cheers
