Example use case

[Sam Halliday]

An example use case of the plugin would be good - the current description is a bit ambiguous.

Could this plugin allow custom <input> forms to be generated to include macros. For example create a text input (already populated with the current date, in a specified format) with a "go" button that then either GET/POSTs the user's input (a single text filed in this case, but could easily have a checkbox or something too)? If so, it would meet my criteria here ​http://stackoverflow.com/questions/11889656
