It was fun while it lasted, but the changes in 3.0 are significant enough for me to throw in the towel on this one. Even in its 2.4 state, the main functionality uses a system that has been deprecated since 2.1 (or maybe 2.0.3, even). In the meantime, the gaps have been filled quite well by other addon authors like Tuller and Maul.

I won't be giving up on action bars entirely. You may see something from me in the coming months, as I did put together an extremely simple button grid for my wife's Beta experience. Plus, I'll have to play with the new Secure Handler system one of these days whenever we're able to update the book.

I'm also retiring ReappearingUnitFrames today, since I don't think the problem it solves has existed for the last few patches.

Look for updates to my remaining mods in the next couple weeks. That is, if updates are necessary... You should try to load out of date addons since some of them have been reported to work anyway.
