The Easiest way to make IE Professional

This is how they define it :

IE7Pro includes Tabbed Browsing Management, Spell Check, Inline Search, Super Drag Drop, Crash Recovery, Proxy Switcher, Mouse Gesture, Tab History Browser, Web Accelerator, User Agent Switcher, Webpage Capturer, AD Blocker, Flash Block, Greasemonkey like User Scripts platform, User Plug-ins and many more power packed features. You can customize not just Internet Explorer, but even your favorite website according to your need and taste using IE7Pro.

Some of the shining features that I specially liked[I've read about this, have not used it and NO I am not being paid from these guys]
- Enhanced Tabbed Browsing
- Mouse Gestures[Oh sweet Jesus of Browsing Opera.. like feature..]
- Crash Recovery[I've used IE for years now, and just like all wise people I know how much important it is, and BTW..it is yet again Opera introduced..if I am not wrong, please correct me if you have more info on this]
- Inline Search[Opera...again?]
- Spell Check[Huh... I could use it...really...]

What I was really looking for though, I didn't get it... i.e. Enhanced Memory Management for IE.. :D
BTW, you can try this little thingy [2.24MB] by downloading it from here. And yes..the sweetest thing is.. it is free... and now I doubt... what would be there revenue stream? A browser add-on that can track whatever do with your browser and sell the data to the highest bidder?
