When Creating a LabVIEW Development Tool and Integrating into the LabVIEW Menus, placing items in the LabVIEW\wizard folder causes them to appear in the File>> menu of LabVIEW. However, there's a known issue that custom menu items in the wizard directory will be displayed in the "File" menu for VIs, but not for projects or in the Getting Started window. IMO, this is a bug. However, I'm guessing that to get this fixed, we should call it an "idea" that needs implementing 🙂 Either way, it would improve the ability of add-on developers to extend LabVIEW.
Item's placed in LabVIEW\wizard folder should show in File>> menu of LabVIEW Project Explorer and Getting Started windows (just like it does for VIs).
