Concept of Pencil 2.0.5 software and its benefits

What are basic drawing tools available in it? Has it any web element, such as Table, Hyperlink, Text? Can I use Div here? What are drag and drop shapes? Is there checkboxes, radio buttons, combo boxes available? How can I change the button name, text or color property? Can I export the document to Pdf, Png, and JPEG format? How to use Cliparts into it from the Internet? What is Diagram Drawing Support in it? Is it windows based software or Can this use any other operating systems? Thank You
