If this is already, or will be, possible in 2.7 or 2.8, please someone confirm. It's a huge feature that knocks Google Docs down a notch when it comes to using Moodle for online essays and such.
Thanks in advance.
This site was upgraded to Moodle 2.8 beta about 12 hours ago. So, what you are seeing is one of the nice new features in Moodle 2.8. See https://docs.moodle.org/dev/Moodle_2.8_release_notes for more.
This is fantastic news.
There are some features of TinyMCE--plugins like Youtube Anywhere, plus Full Screen--that make me prefer it over Atto, but hopefully Atto will grow to include at least the full screen option.
