Notes

Native developers who can help me in implementing native methods for fetching meta data are most welcome, which might give us promising results for all sort of public url's.
Do you have any suggestions in improving the Package/Plugin? I really love to do this kind of stuff. Do contact me here.
If you have used this package in your application, drop a smile & your app link to me, I will be adding those to the same page.
