I have recently been playing with Alfred and especially the Powerpack options that allow you to do some of the most awesome shell hacking with a GUI that I have ever seen.
However, after playing with it for a bit I started wishing that I could quicklook items as I navigated through them in Alfred, so I asked their support for guidance and quick as a flash I got the following answer from Anna:
Quicklook support is not directly in Alfred. With the latest 0.9 release, however, provided you can find a Terminal command that would let you quicklook a file, you could then set it as an additional action in the action list.
So I was slightly disappointed but not deterred – this is after all an App that is so young, the developer has only just gone full time on it (congrats!). I have come to a simulation of what I originally wanted to do and it is close enough to my original idea to be worth sharing – so here is my howto for it.
