Finally after almost half a year of waiting, here is the new, all rewritten version 3.0 of DHTML Menu.
Significant Changes
Embracing the Menu System
DHTML Menu 5.x and 6.x-2.2 used the block system to override the static menu functionality. Version 3.0 ties directly into the menu system using the theme registry. The advantages of these are numerous, but the one you will most appreciate is that DHTML Menu now works with Book Navigation and any other module that works with menu trees.
Working out of the Box
A steady stream of questions and support requests used to be asked by people who simply couldn't turn on the module. The problem was that after enabling DHTML Menu, you still needed to work to get it functional - by replacing blocks, or changing their configuration in 6.x-1.04+. DHTML Menu will now by default be enabled for everything, until you disable it manually. The same applies to cloning menu items as page links - this is no longer an obscure feature configured with an explicit list of items, but globally enabled for all items, and switched on by default. Double-clicking is still around, but can be disabled now.
Numerous other small changes have been made...
