 The TinyMCE text editor has a new look in Moodle 2.6. It has new icons, it works better on different devices and you can toggle between one and three rows you can expand or collapse the toolbar menu. Here we are in a course with the editing turned on and if we click a summary, you see that we have one row of buttons we can choose from and clicking on the left allows us to see two more rows. Clicking again toggles it back to one. There is also a new TinyMCE plugin for managing embedded files which allows us to delete or override or otherwise manage files which have been previously embedded as here.
