Feature Request: Suggested actions

[funkju]

The ability for a feature to be able to "detect" if a given piece of text were relevant to it's action could be neat.

For example, a unix timestamp -> date plugin could detect a timestamp and offer a date.
Or the formatting plugins (XML, JSON, etc) could detect unformatted text that it knows how to format.

The challenge would certainly be performance, but I wanted to log the feature request so I didn't forget about it.
