The big new feature of the roadmap of eZ Publish 4.3 is a new admin interface. The work on it has started with a requirements document and a prototype of a page (download it locally if you want to see it in your browser). jQuery is used in the prototype, I don't know if it's a definitive choice, but as I have already said on that topic, a choice of a framework is better than no real choice (even if jQuery is not my preferred JavaScript framework). I think that most of the big needs are already covered in the document but there are some small details that miss in the current admin interface that I would like to see in the future one :

• Labels of each field should be linked to their related input with the for attribute. That's a very small addition but I find it more than useful in web applications.
• The focused input should be highlighted with a different colour. This is another very small improvement which can greatly improve users experience.
• Buttons in the admin interface should be of a different colour depending on the action they trigger. For instance cancel buttons can be orange, publish buttons blue, remove buttons red, ... The main key here is to be consistent over all the interface.

The edit interface of each datatype should also be considered individually to provide the best interface. For instance, the edit template of a datetime attribute should provide a JavaScript calendar (like with the ezwebin package), the template of a time attribute a button to fill inputs field with the current time, the keyword datatype an autocomplete input (like with the ezkeywords_autocomplete extension), ... Beside an advanced edit interface for each attribute, the data entered in the edit form should also be checked with JavaScript (required or not, valid syntax, ...). In case of errors, fields that do not validate should be highlighted with a message until a new valid value is entered. Obviously, if JavaScript is disabled, a server side check should do the same thing. On this topic, there's also a very old feature request in the issue tracker about the ability to add an help text in the class definition that would be displayed under the edit interface of the attribute.

Finally, a great improvement would be to apply general rules on performances frontend. I think of packing and minifying CSS et JavaScript files (with ezjscore !), using CSS Sprites for design images and use optimized PNG files instead of GIF files. This would improve the user experience by speeding up response time and making the admin interface usable with a slow Internet line
