This idea is easily implemented with a Case Structure. It doesn't make sense to add a Boolean input to every function in LabVIEW. There are a few high-traffic nodes where we have done this, but this is not a node that gets used conditionally with extremely high frequency.
Flush Queue with a Boolean to enable or disable it.
Obviously, the solution today is to put a case structure around the function.
More generally, the same logic can be applied to every single function in LabVIEW. Why not add a boolean input to the ADD function as well?
If you want this, you need to say why you think that this function deserves it more than other functions. Personally, I only use Flush Queue rarely, so I don't see the need.
