Hi Andreas, please help us to improve (update) the documentation yourself.
experimental: because some users found some bugs in certain cases (you can review that yourself also at http://dev.tikiwiki.org/Wysiwyg I guess)
options: might it be that they are hidden until you enable the feature?
Please, try , and improve the docs with what you learned in your trial and error.
Cheers, and welcome to Tikiwiki Community!
