Ever since I made SmallSpotlight, people have been saying "You need to rename that, it's too similar to Spotlight". While resenting that I would have to rename my baby because Apple thought of it first and made it first and distributed it around first and generally did a really good job of it - they were right. I really needed to rename the project.
So after weighing up the options, I came to the conclusion that I shouldn't call it Swallow.. *cough*. Instead, it is now called Searchlight, which conveys the same sort of meaning, has a nice ring to it too. So if you've loaded up SmallSpotlight from the public store - it is now renamed and you'll want to load it again.
As an added bonus I added a parcel search to the engine too - it finds unloaded parcels for you to load (though there's no click or right click action to do so yet)
