+ Amplifies color channels "a" and "b" together or separately / Avoids color overamplification in high chrominance areas / Option to avoid clipping caused by too high color boosting
o Luminance denoising algorithm applied on the CIELab luminance channel
+ Edge sensitive method to preserve as much details as possible
o Color denoising tool applied on the CIELab "a" and "b" channels
+ Classical gaussian blur or edge sensitive bluring of the color channels

Portability :
How can I make RawTherapee portable?
As RawTherapee does not write anything into the registry (Windows) this is a simple task. Simply
edit the file options within the RT applications directory and change the value MultiUser=true
to MultiUser=false. With that no .RAWTherapee folder is created within the users HOME directory.
With MultiUser=true for each user a .RawTherapee folder will be created within his
HOME directory the first time RT is run.
My own opinion :
These apps offers very good treatments for photography's optimization, particulary demosaicing algorithms.
I used it with my Nikon's camera, but also with other jpg or tiff images (scans) .
