Adding Entities without modifying the undo stack

[zograf]

Is there a way to add or remove entities without reflecting that into the undo stack ?

Probably not...

See the boolean arguments for model.start_operation
API: Model.start_operation

.. it's as close as you'll get until the API gets a singleton UndoStack collection class.

The model.start_operation() options are notoriously flaky... but might improve if the API ever gets updated...
