A request continued from the “old” CB7 days and earlier…
Please have Cubase use the computers Operating System “Recycle Bin” for files deleted from the Cubase project pool trash. I like the thought of having one last layer of protection from deleting something that should not have been.
In conjunction with this request please make sure to add a user preference to turn this feature on/off so that users can save some steps if they have the guts. 
My similar request for CB7:
