Not a huge leap but an improvement on events (IMO) would be Named events (ala named queues). Events that can be named but (perhaps more importantly) can work across applications in a similar way that Windows messages can be hooked from an application-all driven from the Event structure. I initially experimented with a similar technology when VIM's where first discovered (although it didn't work across applications). Unfortunately, they broke the downstream polymorphism and made it all very manual with the Type Specialization Structure - so I dropped it. Another is callbacks in the Event Structure. Similar to the Panel Close event, they would have an out that can be described. But getting on to the LabVIEW GUI. That needs to go completely in its current form. It's inferior to all other WISIWIG languages because we cannot (reliably) create new controls or modify existing ones' behaviour. They gave us the 1/2 way house of XControls but that was awful, buggy and slow. What we need is to be able to describe controls in some form of mark-up so we can import to make native controls and indicators. Bonus points if we can start with an existing control and add or override functionality. All other WISIWIG languages allow the creation of controls/indicators. This would open up a whole new industry segment of control packs for LabVIEW like there is for the other languages and we wouldn't have to wait until NI decide to release a new widget set. At the very least allow us to leverage other GUI libraries (e.g. imgui or WXWidgets).
