Tests & Results (more added as we go):

- (as expected) lighter-admin-dropdown-menus wont work with WP 2.7 >> deactivated

- Simple Tags needs tweaking in order to work (not true anymore with versions above 1.6):

• OPEN FILE simple-tags.php AND FIND LINE CONTAINING
  if ( strpos($wp_version, ‘2.5′) !== false || strpos($wp_version, ‘2.6′) !== false )
  {
• REPLACE WITH THE LINE BELOW
  if ( strpos($wp_version, ‘2.5′) !== false || strpos($wp_version, ‘2.6′) !== false ||
  strpos($wp_version, ‘2.7′) !== false ) {

and all features will work in WP 2.7 (thanks to “lecactusov” who pointed to this tweak

- the “Unordered List” button does not work as it used to:

• Randomly when clicking it twice (in visual mode) it EITHER cancels the list OR makes a nested list entry
• Consequently, nested lists dont work in visual mode consistently

and you have to end the lists in “HTML” mode as you cannot predict how the button will react

- Nested Unordered Lists dont work in HTML mode either, if you enter the code and save the post, WP insists on changing the code to un-nest the list (which is why I write this entry in the artificial visually done nested list style)
