EasyWeb has a self generating drop down navigation widget. Creating a new directory (nested folder) is just a question of clicking a button and then adding pages to it which will appear in the drop down.
You wouldn't want to transfer your iWeb files even if you could!
EasyWeb creates better coded, faster downloading pages than iWeb and you can enter all your SEO stuff and stats inside the app.
EW uses code injection so that, unlike the iWeb HTML snippet, code can be inserted anywhere you want. You can't just blindly copy over the content of iWeb snippets. iWeb snippets create a separate HTML doc whereas EW inserts the code into the actual page. This makes implementing advanced features a lot easier.
External files can be dragged into the app and referenced with relative paths. This makes an operation that was difficult for beginners in iWeb very simply and fool proof.
iWeb users will find the EasyWeb user interface very familiar although there are obviously quite a few new functions to learn.
One of the huge advantages of this app is the fact that the developers respond to requests for new or improved features very quickly.
Although EasyWeb is still in Beta, it is more than capable of creating far more advanced and efficient sites than iWeb ever could - right now. A large number of beta testers are rebuilding their iWeb sites using EasyWeb. They can easily keep the same overall appearance while adding better features.
