So far I've never used tags until Moodle 3.5 brought them into the question bank which is a great feature. However I find the interaction rather poor.
While on the screen
If the user click save changes no new tag will be added. Instead, one should hit enter, and the save changes. This might me confusing and at worst might prevent users from using - at least they'll need guidance.
Since this is a new feature - at least at the question level - I wonder if couldn't be a better approach. Assuming of course this is might lead to bad UX.
Thanks in advance,
