When I create a new element in my testing dashboard, I can select a Data Expression from a list of existing expressions. However, since I wasn't very creative in naming all of my expressions, I'm presented with a list like this
If I open a specific data expression to review its code, I can't exit out of the Arcade editor and select another expression without starting the process of creating a new element again.
There should be a separate button that closes the editor and takes me back to the list of data expressions in the Select a layer dialog.
