Lockers in Libraries
I'd like to see lockers in the library where students can leave laptops/books when they leave for lunch, classes or anything else. The keys for the lockers can have QR codes on them just as books, and can be checked out like any other material. The only difference is that a student has to return it by the end of the day.
I've seen this implemented in Cambridge University, and it makes life on campus so much easier!
