We often use student ID (currently implemented as our usernames) as a method for searching for and finding a particular student.
Currently in the Fast Finder these do not show up.
It would be great if system admins could customize the format of the items that appear in the Fast Finder search bar. Or at least turn on/off the ability to search by username / email / etc.
I can’t offer a custom search in Fast Finder just yet, but your particular request for Student ID search in Fast Finder has been met by @skuipers in v13. Yeah!
