WYSIWYG editor or builder for Grav?

I just need to know, if there is grav-way how to integrate CKeditor, Visual Composer or something similiar? I found old topics from 2014 talking about Admin pro module, but havent found any.

I need it for two reasons: Markdown is fine but limiting and second, my customers prefer visual builders like WYSIWYG editors used to from previous experience.

Thanks for tips or links how to switch.

Yes, WYSIWYG comes with the Admin pro module, see plans for 2016:

Currently the pro module isn't released yet.

Any idea when in 2016 this will come out? We're waiting for it as well for the same reasons.

i would say 1H 2016.. we're working on it actively now.
