Save file overlay is missing "Don't Save" option for New Operation #268
Description
[EDITED based on Sprint 11 discussion]
A side-effect of Issue #263 is that a New Operation while on a new unsaved file leaves the overlay without a "Don't Save" option.
If a user creates a new file for a quick experiment (perhaps a copy and paste from somewhere else) then decides to start over, thus creating a new file again, the "Do you want to save..." overlay is left without the "Don't Save" option. This forces the user to either save it, or cancel and delete everything (ie: make it blank) to perform a New Operation.
