Comment 2 for bug 337266

Hi! Yes I confirm that the set of functions in the colour menu (which I didn't know) is mostly what I was suggesting as for the feature and capability aspect.

What would be absolutely great it to have a toolbox, just like the actual colour toolbox, to play live with these settings and control exactly what is happening. (As it is right now it's not that easy to use, but the effects are already available.)

Thank you for your time in reading and answering to this suggestion! Best regards.
