Make warning for uploading students before scans more apparent
The scans page shows a warning if students are not uploaded before the scans are uploaded. However, this warning is only shown for a very short amount of time, and does not stand out (blue warning on blue background).
We missed the message and as such no autolinking happened (as the message indicated). To prevent this in the future, perhaps this message could be made e.g. red to stand out more, and stay on the screen for longer (or perhaps even until explicitly closed).
Other than that, perhaps a button to manually start the linking process of all uploaded copies afterwards? Though I am not sure how difficult that would be.
