Since you don't allow the auto-reopen of files that were closed on an app shutdown, please allow the filename and path to be copied so we can at least create a record of what we were working on before shutting down.
As is, your show document properties doesn't allow interaction, and can't handle long file & path names to allow traversal.
This is intended as product feedback. I do not, and will not, be monitoring forums, nor do I care for workarounds. The feature should be in the product, not on the user.
