To put this (and people's hopes) on the right track, I didn't confirm that we will include the extension right after it comes out - obviously there is still a lot to do. I've seen the Flarum issues on this feature and how complicated it be to implement. We're all right, but to not give anyone false hopes, WYSIWYG editor is not coming out anywhere soon for (Free)Flarum. There is still a lot of work to do, and even if the extension does come out (which will probably be a beta version), we will wait for some time until it gets mature and bugs are fixed, so that we can include it at FreeFlarum without breaking forums.
