Includes advanced Image/Media, File and Link handling, plugin support, and an Administration interface for editor configuration.
The options for individual adjustments f.e. reaction to return-key, custom-colors, file-types for link-handling, etc etc. are great. It tooks me a while to explore all user-options, but meanwhile I know where to put a hand on ;-)
Wat I especially appreciate is the possibilty to have different layouts for different (groups of) users. I typically enable nearly all features for power users. For my less skilled users, I have a very simplified subset of functions that appear.
