IE7 Pro Plugins???

Does anyone have any scripts that will work with IE7 Pro? IS anyone here familiar with it. It can support scripts just Like Grease Monkey. I was just wondering if any one new how to develop or convert the current plugins so that I can use then through IE7 Pro. It is a freeware just like Grease Monkey and for those of us that do not use Firefox for various reasons it lets us do a lot of the same and is compatible more so with other applications. Hope I can get a response on this.
