Assignment display changes that are not included in April release notes


Why was the date when the assignment feedback was last saved changed to a tooltip in the last update?
I can find nothing about it in the release notes.
We use that date for many reasons, like instructors knowing where they left off Grading/ reviewing assignments, especially during exam time, which is right now. We use anonymous grading and have developed a method to bulk upload the exams as feedback which sets the status to saved as draft. Without that date showing on the page, many many more hours will be needed to grade in what is already a tight turn around time. Can this be changed back?
