Kudo's on a great product!
I'm looking for an MSI product to replace InstallShield that is cheap and simple to use for all our project teams. Advanced Installer seems to be a good bet.
The biggest problem I currently have is with the organisation screen. One of our products really has a lot of files (hundreds) and when trying to move my components into features, I could only drag my component to the top of the screen but couldn't get it far enough to drag it into the feature. Perhaps auto-scrolling to the top when dragging will help.
I later discovered that I can scroll up with my mouse's scroll button, but this is buggy (and not too intuitive) - it dumps duplicate pictures of the component while I scroll up.
Perhaps a right-click on feature and select which components go into it will help.
