I am looking to add a custom button to the gradebook page. The button would simply launch an external URL (to our home-grown student alert system). In the future I might explore better integration but for now a button that provides a visual pop but simply launches a URL will do.
I was able to follow Mike Cowen's post on Collapse & Expand Modules to create a dummy button on the modules page but do not have the technical skill to translate that logic for use on the gradebook page.
Can anyone help?
