As a new user of Canvas, I am frankly flabbergasted that there is no Export button on a page presenting tabular data, such as People. This is hugely helpful, for example, to load student emails into into a spreadsheet and on, say, to a Google Form send list.
There is a rule of thumb in scientific data webapp UI design: if there is tabular data, there is an Export button. I think this rule of thumb should be adopted throughout Canvas.
If not, I'd be very interested to hear why Canvas is intentionally hobbled in this functionality.
I realize there are workarounds. Workarounds are not responsible UI design, they are just that - working around a software failure.
