Cache schedule page
Summary
Each time the user navigates to the schedule page, a new request is made to load the user's schedule from the CRNs in their cart. This is unnecessary and makes Schedules feel slower and less responsive.
Instead, save the HTML response of the current schedule, and use that when the user navigates to the schedule page if their cart has not changed.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
