This request was initiated by Lino Alves in our Brazil office.
Some CKEditor plugins ("maximize", "print", "save") do not work with inline mode. It would be good if this info was available on the plugin list present on https://dev.liferay.com/develop/reference/-/knowledge_base/7-0/ckeditor-plugin-reference-guide
Please see LPSP-352 for more details.
