The upcoming 3.4 release will bring lot of new functionality. Some of that has been developed by core members, but many contributions were made thanks to Google Summer of Code program, where five students were working on improving phpMyAdmin. If you want to try new features, you can do that on the phpMyAdmin demo server. And I will introduce them in series of blog posts.
One of long requested features was ability to change configuration for each user. And phpMyAdmin now has it. If you have configured the phpMyAdmin configuration storage, settings are permanently stored in the database, otherwise in session and optionally in web storage in your browser.
You can configure any aspect of phpMyAdmin not affecting security or server performance, like confirming DROP queries, default export settings, user interface tweaks and so on.
This feature was implemented by Piotr Przybylski during Google Summer of Code 2010.
