1. There are various things tests that can just have intentions added
into them, like filters and such like, add intentions to these
2. Start thinking about being able to negate steps easily, which will
lead on to a cleanup of the steps
This enables people to enter things using the mouse to paste for
example, plus possible other things.
As an aside it also answers my query regarding `fillIn` for testing,
nothing needs to be actually _typed_ anymore! Doh
