- Save a layout called wtf001
- Run this command from the root directory of your computer (not your user!)
sudo find . 2>/dev/null | grep "wtf001"
- That's it

but we don't know if that's subject to change (probably).
Disclaimer: this isn't good. We need to populate the File menus on Mac, at least, and hopefully locate the stuff under your user directory.
