Hi Laurent,
Thank you for your kind words! I am doing my best to make WireframeSketcher a top wireframing/mockup tool.
I think a user contributed gallery of components is a very good idea. The trick is to find an approach that is both simple and flexible.
I am thinking about setting a Posterous blog where users can send their mockups by email. I think I could easily add an interface to access this blog directly from Eclipse and interoperate with WireframeSketcher.
Please let me know what you think.
