It's now definite that the WP 3.0 release will include a new drag'n'drop menu/nav setup -- they're "integrating" the WooThemes "Custom Navigation System".
Sorry, but the only link I have re this to the WP Facebook Fan Page blog/notes -- apologies if you're not a FB member and can't link thru to this:
FB WordPress Notes / Menus, the Merge, and a Patch Sprint!
I'm wondering if the extensive changes to the WP menu setup will break the ATA appearance options. I always upgrade my version of WP pretty quickly after they put them out, but I know this time around (sometime in May), I'll be waiting to hear from Flynn or Juggledad that the "coast is clear" and upgrading is safe.
