Thanks for adding the disk folder location path by rt-clicking on the title in the editor pane. See video attached.
Happy that you’re happy – but we can’t take credit, that’s a macOS feature you get when you write Mac-assed Mac apps like Lettera 
Hah!
Yea, I saw that last night with another app and then realized exactly that. I wasn’t sure if it happens automatically by using the MacOS window UI widget or you have to enable something to make it display.
Glad to see it either way.
