Anyone with access to deleting a project, should be able to undelete that project without changing the ownership of that project.
If I accidentally delete another person's project file, and I am tagged as the person who deleted the project file, I must then contact the owner of that project to undelete it, even though I had no trouble deleting the file, and the system knows it was me who deleted it. The act of undeleting a project, in that case, would make me the owner of the project and therefore, it isn't a permissible action. This seems counterintuitive and inconvenient to a person with a project in a folder with multiple users, who could delete items at any time, and not undo it.
i.e: Anything that I can delete, please allow me to undelete that project back to where and who it original belongs to.
