The Style Gallery is a window which shows a catalogue of possible formatting styles as pictures, so that you see exactly how the style looks. The style can be dragged onto a branch or applied to the current branch by double-clicking or using the Enter key. The motivation was to reduce the complexity of the formatting process to its absolute minimum - in this case, choose a picture and drag it in. At the same time, it reduces the amount of text required in HeadCase by providing an image of the style rather than a description or set of cryptic properties, thus reducing the effort required to issue language packs.
