I am passing along a common feedback item from our students regarding the iOS app.
Bring back the calendar colored dots. Where before the iOS app calendar featured colored dots on a given date representing different courses, there is just one blue dot now to indicate content from any course. Students appreciate the additional insight at-a-glance that the colored dots previously afforded.
I understand there may be an accessibility concern. Software should not use color as the only way to communicate something. However, the current notification indicator is a single blue dot. Restoring multiple colored dots would not convey any less meaning than the current implementation of a single blue dot. For the color challenged, one dot or multiple dots still mean the same thing - the presence of at least one item for that calendar date.
The loss of this feature in the iOS app is one of the main complaints I hear from our high school students.
