Content creation

Can anyone point a way to do this? By following the instructions at https://h5p.org/adding-text-editor-buttons I have built a module with an after_build hook and manage to add tags and buttons to the h5peditor tool bar, but I cannot seem the add the Source (i.e. sourcearea) button plugin? I ahve downloaded the plugin and the js to load it is being run but the H5PEditor.HtmlAddons.text.sourcearea function id never breing called? Any ideas?

Thank you

I work for an e-learning site and I'm evaluating using the course presentation format as a fallback for users who cannot load our existing flash-based and HTML5 based interactive review sections. Because the users who report trouble with loading the review sections are almost entirely iPad-based, it would be ideal if we could design the course presentations in a 4:3 aspect ratio.

I am trying to find a plugin which will let the users rearrange the jumbled up paragraphs. Is there any H5P plugins to do this?
