The first usability release, Acai, hit Wikipedia and sister projects this afternoon. The new skin, Vector, and the enhanced toolbar can be turned on from the user preference under “Appearance” and “Editing”. Search result page now has a new layout with less daunting information. Vector is only available for left-to-right languages at a moment due to IE6 incompatibility. However, the enhanced toolbar can be selected from all languages and the new search result page is enabled globally. We could not roll out two features we had planned. First, warning messages for unsaved changes when a user switches away from the edit tab did not work properly thus they are disabled. So please be careful when you switch away from the edit tab. Secondly importing language specific configuration for special characters were not graceful, so we disabled special character function from the toolbar. We are working on the fixes and plan to roll them out as soon as we have stable solutions. The usability project wiki has Vector and the new toolbar as a default, so if you prefer to check them out without changing your preferences it is a good place to visit first. Let us know what you think. We would love to hear from you.
