A stop or cancel button on imports could be a lifesaver for all Canvas users. I see it being helpful in scenarios such as:
- You start to import the wrong content
- You accidentally selected "All content" when you intended to choose "Select specific content," or vice versa
- You forgot to adjust or remove the dates
- An import is stuck in queue, and you want to cancel it before starting another import (This would prevent the queued import from running at a later time and overwriting course content.)
