This is the Poodll widgets icon.
The reason you don't see a PoodLL widgets icon is probably because it is not selected in the list of icons to show.
If you are using Atto and dont see Poodll at all on the toolbar, you need to add "cloudpoodll" to the icons displayed in teh Atto Toolbar settings in the site administration.
If you see Poodll icons on the toolbar but just not the widgets icon, there is a setting in the CloudPoodll for Atto's settings page for that.
If you are using TinyMCE then there is no PoodLL widgets dialog. Until we write one of those you will have to either:
- make the poodll filter strings by hand
- create a special Moodle user for Atto
Regarding ii), you can set the preferred editor per user in their user preferences. So you would create a user with the same access rights as your own, and set their editor preference to "atto." Then when you need to add some widgets, log in as that user to do so.
