I"m not sure it's conflation only. Many seem to be focused specifically on the fact that LabVIEW GUIs don't look like the latest hyped Office version, which of course will be again different over 2 years when yet another modern style design guide claims that everything needs to be high contrast again, or maybe alpha shaded with psychadelic animations (you need to find reason to sell high end GPUs to spreadsheet jugglers).
Your second point is indeed one thing I feel LabVIEW could have made more advances. Dynamic control creation while indeed complicated to get into the dataflow paradigma of LabVIEW would be possible with the VI Server reference model, although it would not be classical dataflow programming anymore for such GUIs at least for the part that you use such dynamic instantiation in. XControls was a badly executed project for an in principle good idea, Splitters are a God send for more dynamic UIs together with Subpanels, but to try to edit splitters once they are placed on a frontpanel really can be an exercise in self control. In doing so I feel the same frustration as when I'm forced to edit some Visio drawings. The editor almost seems to know what you want to do, because it always does the opposite of that, no matter what.
