NoxuNote uses EditorJs (https://editorjs.io) as WYSIWYG rich text editor.
EditorJs supports plugin, enabling to add new type of block to insert on the text editor.
Every plugin are declared in .js independant files and are loaded by EditorJs. They are automatically compatible with the editor's serialization because the content produced with a plugin also serializes to JSON. In so, there is no need to update NoxuNote nor the MyNotesAPI.
