chm file integration with Dreamweaver MX

Hi, I've working in an extension which gives support for the chm file in Dreamweaver MX. The extension adds a button in the insertbar's PHP tab to open the file. Also it gives contextual help for functions found in the document code: you can select a function, right click and select "PHP Function Reference..." and the chm file will open in the related page. You can see some images at: http://www.tecnorama.org/document.php?id_doc=49 (You will find a link to have the page translated: it's in Spanish but the extension and the files used are all in English.) Thank you
