Not to be smarmy but:

operation_class->name        = "sdv-unsharp-mask";

and leave the standard unsharp mask.  

The current unsharp mask uses radius, amount and threashold. The new one uses 
scale and standard deviation.  The function it is performing an unsharp mask 
but it's done the equivalent of going from Farenhight to Kelvin without telling 
anyone.  This results in somebody using one image editor not being able to spec 
actions for somebody using a different editor.  This can be a big deal where 
multiple photographers are trying to produce a consistent output (for example a 
primary and secondary shooter at a wedding).

As for Qtpfsgui, the autoalign doesn't work, even on tripod mounted shots on a 
still day.

Let me give you an idea: edit the source code and send us a patch
('diff -u' is your friend)

You want this file:

Qtpfsgui is your friend :-)

You mean you want all those noise reduction plug-ins and scripts
floating around GIMP in the bundle or some particular one? Could you
probably be more particular about that? :-)

I'm not saying GIMP developers will do what you say (I'm not in
position to make any claims regarding development process), but at
least you could start with review of existing solutions for GIMP
(GREYCstoration, Wavelet Denoise etc.) with samples and
recommendations. That would be a good start. Just telling people
something is missing and not providing enough information is not quite
helpful ;-)
