Next article highlighting some new features which will come in phpMyAdmin 3.4 is about more little changes. You can try them it out on our demo server. Or just wait few hours for first alpha release of 3.4.
The user interface cleanup is partly connected with previous changes, because some functionality simply required more Javascript (for example editor for ENUM/SET fields). Besides these there were major changes in export and import pages, which now should be easier to understand, hiding advanced options from unexperienced users, while still providing ability to change them.
This feature was implemented by Lori Lee during Google Summer of Code 2010.
