IIRC, the folders for Applications, Demos, Desktop applets and Preferences would exist in the ~/config/settings/deskbar/menu but would be empty. So would I would do is, I’d leverage the old menu_entries symlink to point to menu and then I would symlink all of the apps, etc… from system, which would give me the ability to configure those folders in icon mode, etc…

I’ve been meaning to write a bash script to automate the whole process.
