General developer forum
Stuart, have you taken a look at the WYMeditor that was mentioned in that article? It seems to have more features than wysihtml5 (and even supports plugins), but still has more of a focus on the structure of the document. While I have some complaints about how it works (e.g. there seems to be no way to switch a list item to be a regular paragraph), it seems to be a good start.
organizing site content is really a much larger issue than just replacing a wysiwyg editor with a less advanced editor. Changing editor does not solve your problem.
What you want to do at Sussex University is to restrict user input so that your pages of moodle could look something like this:
In wikihow.com (example) you can edit separately different parts of content but site administrators (or the cms/lms/etc) have preset (layout element) options that users can edit for example like this
Still most likely BBC could not use "wikihow-content-format" and Wikihow could not use "bbc-content-format" directly because both sites might want to have personal structure for their "articles"... = content.
If you want to change moodle to a "standard-type-content-management-system" the best (trivial) way to do it quickly is to re-write all necessary activities, add some new course format (Sussex article format) and set your site to use only this special course format and custom activities, not the core ones. These custom activities can have as many extra text fields as you like in as many "templates" as you like and you can implement whatever editor to these text fields if you like.
Presentations like http://www.hannonhill.com/news/blog/2013/new-webinar-series-progressive-enhancements-to-improve-content-editing-and-re-use.html are great but in the real world teachers use mostly offline tools like Word, Excel or Powerpoint to create printable course material / presentations / pdfs or they have hundreds/thousands of different kinds of documents in their hard disc and they often want to copy/paste some parts of those documents instead of rewriting every single word of new text. The facts that all mobile apps don't support all features of corresponding desktop tools or some pdf readers don't support all features of original Adobe pdf files does not prevent teachers creating content with the tools they like and have used. When a mobile user installs a mobile app she/he expects that it can do certain things the same way as desktop tools but she/he also knows that many tasks can't be done with mobiles - and they can find a desktop tool edit documents if they need to do it today...
@mauno - please stop underlining text that isn't a link - i understand its a beginners mistake, but we all have to learn sometime.
@Stuart - Please use capital letters correctly. I understand that is a beginners mistake too, but we all have to learn sometime.
