Time to wrap up the year, I think. I released 2 more small plugins of mine on github and the MooTools forge.
A plugin for small tag lists input. Also, provides an ajax auto-completion sub-class that can be used as a standalone anyway.
Example with ajax tag completion: http://fragged.org/mooTagify/Demo/
The plugin is quite easy to setup and you can style it via CSS only or via the many options available to the 2 classes that run it.
This is a combination of several things: the flexible modal markup experiment by @csuwldcat (Daniel Buchner from Mozila), implemented in the Modal.Base class and the Modal.BootStrap class.
The BootStrpa itself (not to be confused with Twitter’s BootStrap) provides a flexible implementation of content in the Modal window through HTML5 element mark-up only, including support for ajax links, grabbing content from elements on the page or setting pure text, even image support (pseudo-lightbox). It also works with location.hash so you can have page.html#terms_and_conditions as a link, if there’s a matching element managed by the BootStrap instance on the page.html, it will open it automatically for you. The modal will ALWAYS stay in the middle of the screen, it has support for responsive design with minimum width and max width as well as support for CSS3 transitions over js morphing of style properties (if available). Very useful for things like terms and conditions, privacy policies, quick contact forms, questionnaires and so forth. It also has support for buttons in the footer with custom events fired in the instance, so its flexible for scripting.

Merry Christmas, everyone and a Happy New Year – unless I release anything in-between.
