Xi’an Jiaotong-Liverpool University recently asked the team here at Catalyst about the possibility of improving the annotation UI to help their teaching staff - they came to us with two main requirements:
1) Page Scrolling - allowing normal page scolling instead of the navigation buttons.
2) The ability to undo.
We put together a high level proposal that covered an approach we think makes sense and we wanted to open this up for further public discussion - so here it is: https://docs.moodle.org/dev/Improve_Annotation
Please feel free to comments here - negative and positive comments are both really welcome and may help to shape the proposal further.
Since we put this together the team at Warwick have managed to develop a patch adding undo to the existing annotation plugin which is awesome! (see MDL-60299).
This is still in the early proposal stage and Xi’an Jiaotong-Liverpool University hasn't confirmed if they will have the budget to fund this yet, but if you think this is great and want to help - there are a number of development tasks that could be looked at prior.
