While the idea of differentiated assignments is a good one, the sign posting for differentiation could be better. When a student has to resubmit work inevitably a new date has to be assigned. This can cause confusion for a student who has just submitted and assignment to the same submission slot. I feel that a simple update to the assignment slot itself to display information held in the rollover popup, on page.
Attached it a snip of what presently happens.
The summary of suggestion is:
As an option (part of the Canvas assignment settings) information held in the multiple dates roll over is not 'hidden' but displayed explicitly on the assignment slot.
P.S. unrelated to this idea but to the posting of this idea no idea what bearing 'labels' have as there isnt one for assignments
