I have no idea what this means, can anyone clarify?

If I understand correctly - I may be wrong - for example if Text object is selected then on toolbar there are Font, font size, bold, italic, underline and many more option. User pmatulka would like ot have this option in pads like Tools, Palette, Images, Layers or History. So to have additional docker/pad for this tools - Gimp has this kind of functionality (additional pad for options).
