CKEditor to TinyMCE

[bemoody]

As we've discussed, PhysioNet's current rich text editor (CKEditor 4) is unmaintained and should be replaced. This branch replaces django-ckeditor with django-tinymce (https://github.com/jazzband/django-tinymce).

Further work is still needed, but it should be usable at this point, so I invite folks to try this branch out and see what you think of the UI. TinyMCE (like CKEditor) is highly customizable, so this is a good opportunity to point out anything you dislike about the toolbar, menus, keyboard shortcuts, look and feel, etc.

This breaks badly in old browsers: using Firefox 78, the editor mostly seems to work, but upon trying to save the form it crashes (which the user won't notice unless they are watching the console) and apparently submits blank content.

Can we raise a warning for people with old browsers or would you prefer to explore alternatives? From googling, the latest version of CKEditor is popular (though I'm sure it has its own issues).

I'm certainly willing to look at alternatives & that's part of why I wanted to post this as a preview.

But it also should be possible to add a workaround (my thought was to fall back to a plain textarea on old unsupported browsers.)

Personally I'd rather just ask people using outdated browsers to update them!
