MIT Open Learning has been using this extension point for some time now in its Rapid Response xBlock, but the UI doesn’t work in the Course Authoring MFE. We’ve opened a PR to address this, and it would be helpful to have some documentation to explain the context for product review and code review.
If there is no documentation, we can write some, although I need guidance on where such documentation belongs.
I’m not aware of any documentation. I didn’t even think the feature was fully implemented tbh.
Alongside documentation, if this is a feature we intend to support in the future, it would be great to have examples of asides in the sample course for authors and the devstack default course(s), to raise awareness and facilitate easier regression testing.
Asides were fully implemented, but the implementation on the studio side predates a lot of changes and certainly predates the MFEs. They basically do not work at all in studio.
Looking through the history of Asides, I see that they were developed initially to support tagging of XBlocks. @braden or @dave, do you here know if that is still part of the implementation plan for Content Tagging?
