This was added here [0], but only for layers that have unsaved edits.
Also, a red pencil legend layer icon was added to indicate when a
layer has unsaved edits. Let me know if you have any comments on or
suggestions for their implementation.

The 'Save All Edits' functionality will be added to the project close
notification, when layers are found to have unsaved edits (currently
just shows some red text that can be overlooked).
