I have been doing this with the right-click framework since LV9. I do not use the RCF any more but I tested the code in LV12 and it still works. Adding the conditional terminals was easy, but the subdiagram labels are a bit of a trainwreck. I'll have to hack around that.
Overall it was pretty easy to implement, about an hour (it would be less if I were the world's fastest LV programmer).
The native replacement would be nice, it is faster. My scripting version breaks a ton of stuff and then fixes it, which I still enjoy watching in a weird sort of way. There is that moment of anticipation when everything is broken, followed by relief.
But to be honest I do not support this idea as is. I'd rather fix the native replacement to maintain wiring to the conditional terminals. Then add the scripting support.
There is a comment in one of my VIs though: (edited for family viewing)
WHY THE F#$K IS THE LOOP COUNTER NOT INHERITED BY THE LOOP CLASS???!!!!
I was tired of casting to the specific loop type to get the reference. The same could be said for the conditional terminal now that they all have one. I would move it up the hierarchy and make it an error to write false to the While Loop HasCondTerm? property. But I digress.
