It is also quite interesting that if new style is created and is then saved in a subfolder of the styles folder Styles, that style, registered in the styles panel will recognise the style in that subfolder and will complain that the stle could not be loaded if this style file is removed from the subfolder. BB itself can read from the subfolder. It seems only the Style Picker that is designed to to look for these style in single folder. This is rather perverse for a utility that is meant to list all styles.
