In the new "Student Enrollment" editing (as of the 1/9/20 release), our period names are cut off which makes it MUCH easier to make a mistake when editing a student's schedule. We could see them just fine in the old "Manage Enrollment" view - please adjust the defaults to make them visible like before!
This has been updated with the 1/28/20 weekly release. The columns will default to a width that shows each block name.
