For dynamic applications that have decoupled main and GUI programs and that have large numbers of indicators, it is difficult and very limiting to update or read front panel indicators by staticaly wiring to or from them. It is much more convenient to read from or write to them by reference using a property node, but that incurs a performance hit in your main application that is doing the writing or reading as it has to thread swap to the UI. It would be neat to have a high performance way to dynamically read or write values to front panel indicators by reference without thread swapping or having to run the main app in the UI execution system. A super property node of sorts. I don't care about other properties so much as I do the actual value of the indicator/control. This would open up the door to creating dynamic GUI frameworks that have to adapt to many test configurations on the fly without the need to rewire tons of front panel objects or maintain a bunch of unique GUIs.
Functionality available in LabVIEW 2013 and later with the 'Set Control Values by Index' and 'Get Control Values by Index' functions.
