Models that are marked as deleted are put in the deleted tab and remain there until:
- they are permanently deleted by pressing the Delete option
- they are restored by pressing the Restore (undelete) option
- or, until some period of time has elapsed and the models are permanently deleted.
The (permanently) delete and restore options can be done in either way:
- by selecting the model(s) and pressing the Delete or Restore (undelete) button at the top
- by clicking the
button to the right of the model and select Delete or Restore (undelete) 
button to the right of the model and select Delete or Restore (undelete) 
Warning: Make sure that you really intend to permanently delete your model(s) as this action can't be reverted.
