I'd like to be able to add custom buttons to the GIMP toolbar.
For example to be able to add the "Hue-Saturation Tool". There is a youtube video (GIMP Tutorial: Customizing Main Tool Bar) that shows how to do this in GIMP 2.4 via "Configure this tab"->Add Tab->Tools.
And then down to "Tools" option:
However in gimp 2.8.22 there is no "Tools" option in the pop-up menu. How do I add these tools in GIMP 2.8?
