This is one of those ideas that hits you like a bucket of wallpaper paste, and you think “Why on earth did no-one think of that before?”
Choosy is a utility for anyone who uses multiple browsers and wants to open certain links in certain browsers under certain circumstances. Web developers will know what I mean, but there’s something in this for normal people, too.
For example, if you’ve created any stand-alone webapps using Fluid, you might want to open some links in one or more of those apps. Say you’ve got a Fluid app for your Google Docs. When an email arrives with a link to a shared document, Choosy will let you open it in the right Fluid-created app, not in your default browser.
I suspect developer George Brocklehurst might be a name to keep an eye on in future. What’s the next smart idea up his sleeve? Watch out for more bucket-of-wallpaper-paste moments.
