Mea culpa but as noticed by tsala eagle eyes, the custom theme developed for the Learn Moodle Basics MOOC does not have the activity linking navigation now standard in Moodle 3.4 (I didn't think to check when testing the site as I kind of assumed it would have it)

(The theme is set in config.php so not possible to change to standard More)

The MOOC starts on 8 January so I realise it is too late for then but it would be good if the theme could include this activity navigation for future MOOCS. 

Pinging barbararamiro and mudrd8mz as you both worked on the previous one. Thanks for any help in 2018
