About Bettersubbook
Make the Subbook shift board work for you...
Bettersubbook is a free Chrome extension for University of Illinois Campus Recreation Aquatics staff. It adds search, sorting and filters to Subbook's list of open shifts, reads your own schedule so it knows what you're free for, and fills in the Add Request form for you. You always press Subbook's own Submit button yourself.
UNOFFICIAL: Bettersubbook is an independent project. It is not made, endorsed or supported by Subbook, Campus Recreation or the University of Illinois.
