Specifically, it lets you edit more than one node's taxonomy within
the same form.
This patch also removes the behavior where taxonomy remembers your
last choice for a given vocab and automatically selects it for you.
That is poor behavior. If someone changes a date or author in a
node, he is likely to inadvertently add taxo terms using with this
'feature'.
+ Changed menu.inc to generate two separate lists instead of nested lists:
that seems to be the only alternative to get rid of absolute positioning.
+ Changed the tabs code to be more sexy and put the code in misc/drupal.css
so all themes are automagically updated.
CHANGES
-------
+ Introduced tabs. First, we extended the menu system to support tabs. Next, a tab was added for every link that was (1) an administrative action other than the implicit 'view' (2) relevant to that particular page only. This is illustrated by the fact that all tabs are verbs and that clicking a page's tab leads you to a subpage of that page.
+ Flattened the administration menu. The tabs helped simplify the navigation menu as I could separate 'actions' from 'navigation'. In addition, I removed the 'administer > configuration'-menu, renamed 'blocks' to 'sidebars' which I hope is a bit more descriptive, and made a couple more changes. Earlier, we already renamed 'taxonomy' to 'categorization' and we move 'statistics' under 'logs'.
+ Grouped settings. All settings have been grouped under 'administer > settings'.
TODO
----
+ Update core themes: only Xtemplate default supports tabs and even those look ugly. Need help.
+ Update contributed modules. The menu() hook changed drastically. Updating your code adhere the new menu() function should be 90% of the work. Moreover, ensure that your modue's admin links are still valid and that URLs to node get updated to the new scheme ('node/view/x' -> 'node/x').
+ Introduced two new functions:
1. form_set_error($name, $message): files an error against the form
element with the specified $name.
2. form_has_errors(): returns true if errors has been filed against
form elements.
+ Updated the form handling:
1. The form_ functions will add 'class="error"' when a form field
has been found to be erroneous.
2. The error message is passed to theme_form_element() when the
particular form field has been found to be erroneous.
+ I updated the user and profile module to take advantage of these new
functions.
+ IMPORTANT: the _user() hook changed. The 'validate' case should no
longer retun an error message when something goes wrong but should
set it with form_set_error().
