Suggestion: delete confirmation fot certain dirs

I don´t use the standard delete confirmation of Windows, since it´s annoying most of the time. But i almost use the keyboard for most Opus actions, so there is always some danger to accidentally hit the del button on large important directories. It would be good to have some option, to protect chosen folders from deleting, the deleting command would bring up an custom dialog, or even a password dialog (short password for confirming each delete or overwrite).

There is no need to really protect the data by attributes or Windows´ security functions. It could be a simple checkbos "write protection" in the folders settings dialog. What do you think about this idea?
