Easily add custom Flattr widgets to your posts and pages using shortcodes!
This is a widget that allows you to quickly and easily create a flttr widget within posts and pages using a simple shortcode. The advantage of having a shortcode is that it can be customised for every use. The short code has lots of customisability and can be used in a very basic way or with more advanced features.
This means that you can insert widgets that will Flattr pages other than the one you are on (for example some external content) and it will also allow you to set the Flattr User ID per widget meaning you can have multiple widgets for multiple people, or allow blogs that have multiple authors to add a Flattr widget that will flattr them (rather than the site) for their content.
