Prototip 1.1.0: “You can now open, close and toggle tooltips using any mouse event. Keeping your tooltips open adds a new dimension to the library, allowing tooltips to be used in new ways. This release also introduces close buttons, delay and the option to add your own close links inside your tooltip text. An improved CSS model makes it even easier to style your tooltips.” – Note that this is a preview release as Prototype 1.6.0 final isn’t out yet 😉
