Еcли все это будет реализовано... Implement unlimited depth categories (but not multi-mapping). Refactor the user management system and make it more extensible (eg, allow custom user fields). Implement a comments system (including pings and track-backs). Implement queued redirects (allows you to, for example, return to the previous page you were on after you edit something). Refactor parameters and make them more extensible (for example, plugins could allow you to add additional custom parameters to articles). Finish MVC-ing the Administrator components (we need lots of help here). Implement CAPTCHA helpers for any form. Implement systems whereby external authentication systems, such as LDAP, can map to our new Joomla user groups. Re-implement the ability to select multiple categories for some views in com_content (was in 1.0, got dropped in 1.5). Implement a database driven installation log. Refactor JError. Examine the PDF generation system in detail and see if we can make it work properly (otherwise we will look at dropping it if we can't make it work well). Localise the Invalid Token messages. Drop the Polls component because the quality of that extension is pretty bad and there are much better third-part alternatives available. Convert all layouts to semantic, XHTML Strict. Convert of ini-based "params" fields to use JSON instead of INI format (huge technical and performance improvements). Note, the language files will remain in INI format.
