Plist Pad is a simple property list file editor for Windows (Linux and OSX builds coming soon!). Plist Pad is currently just an alpha build of something that I’ve hoped would materialize on the internet for some time now. As far as I know, there is no good Plist editor for Windows that looks and acts like the built-in OSX Plist file editor. Well, hopefully Plist Pad will change that!
I'm not sure this is far enough along for a broader audience yet: "Please note that Plist Pad is currently in a very early stage of development. I’ve tested it on a dozen or so plist files of various sizes but please assume that this application can possibly mangle your Plist files." (Emphasis from the publisher themselves)
Sometimes, the impossible can become possible, if you're awesome!
