- When users click on the pen symbol, replace the box by an editor so that users can change the content
- Change the type font in the non-selected box to be the same as in the editor, so the lines stay the same
- The editor can be closed by clicking on the "Leave editor" button. The boxes will be text boxes again (with the usual font), only that the text in the selected box is now changed according to what was changed in editor mode
- When the page is saved, the selected changed version is saved.
