Moodle in English

Someone forked the Github source code for this plugin and fixed the problem I believe. See https://github.com/Zyten/moodle-qformat_canvas. I compared the source code and the offending function is implode(), where the order of the arguments has changed in PHP (see a comparison of the code changes). The forked copy has fixed this. I haven't tested it though.

No, you can add multiple buttons to the Atto toolbar in a single plugin, see for example the built-in "Link" plugin, which has 2 buttons, link and unlink. Source code is at https://github.com/moodle/moodle/blob/main/lib/editor/atto/plugins/link/yui/src/button/js/button.js, line 120

Hi Justin, 

I don't think this is feasible, because OneDrive doesn't allow anonymous people outside your Microsoft 365 tenancy direct access to OneDrive files. As far as I can tell, if a student didn't have a Microsoft 365 account for your organisation, you would have to explicitly include their email address when giving access. They then receive a one-time pass code to access the file.

I believe the normal procedure is that the Moodle site would be configured to use Office 365 for Single Sign-On, so students would already be logged in to Office 365 and thus OneDrive, before they accessed a link to a file on OneDrive. If this is not the case, then they would be prompted to log separately to Office 365 the first time they accessed any of the services included, but wouldn't be asked each time they accessed a different OneDrive file in a single session.

You’re double-escaping the HTML by using entities inside the CDATA section, just use standard markup instead.
