ColorMaster v4.4 Released adds Previews for Custom Looks

Hi everyone!
I just wanted to tell you that I have released the next version of the ColorMaster addon, v4.4. This release allows previews to be generated for any custom looks, as well as the ability to regenerate previews for all of the looks. Also, Filmic Blender has been updated to the absolute latest version and I have added some tools to help when working with a linear-based workflow. In addition to everything, there are the usual bug fixes and performance enhancements in there as well.
Thanks!
