Hi Gilles,

now I had time to look at the new plugin.

Thanks for porting, looks good on a first sight.

A German one? ;)

How much work would it be to provide the more sophisticated options of 
the original code? Especially deciding how much denoising on each 
channel should be done was something that I really liked about the gimp 
version and that's not possible right now in your port.

If you want to prevent users from having too many options right after 
starting the tool, we could think about using to tabs for the options: a 
simple mode like it is now and an advanced mode, where you can specify 
the settings for all the color channels.

One more minor thing I noticed: Right now there is a slider for 
softness, but what it actually does is the opposite. If you move the 
slider to the right the image is sharpened, not softened.

Hm, I wouldn't miss the old tool too much. ;)
