For a better style management!

Hi,

I would really appreciate having a better styles management that would for instance include a "style gallery" that would list up all styles used in a map, which would simplify style management. I would suggest at least 3 features in this style gallery:

• one button would apply the selected style to the selected objects,
• one button would highlight all objects on the map that use the selected style,
• one menu would enable editing/duplicating/apply selected object style to the selected style in the gallery...

More ideas?
