I installed the NE Plus version today.

Load of my Yarn node program worked fine. The 4th datatype was added to the Math nodes, with no connections, and the program ran just fine.
After saving the program, it loaded into the old NE program, but the new function datatype inputs showed up, and the nodes were Red, and program would not run.
Old programs still run in the old NE program.

ps So far I like the new version, and the additional capabilities seem desirable and possible.

Edit upon closing and re-opening MoI, the New shortcut key is no longer installed (assigned new code)...so it does not work.
Edit: redid shortcut key, and now the new programs works, and survives re-opening of MoI.

The shortcut resizable window setting of the new version does NOT seem to work.
