The link is dead, I'm sorry about that. I will re-upload the addon. There are still some rough edges in the code that need to be ironed out. Particularly the configuration is quite difficult to do, and it's not possible to configure the colors. I'd like to fix that before I upload the addon again.
My other projects (IFrameManager, IFrameFactory, Serenity, CommChannel) are on github, too, if anyone is interested. Though not all are guaranteed to work with WoW-4.x. IFrameManager is, so you may want to update that, too while you're at it (https://github.com/wereHamster/IFrameManager/downloads)
