The NLU popup/dialog, at least in the OSX desktop app, is not resizeable. That’s so 2010s. This whole thing needs to be resizable and the fields need to proportionally expand/contract. This fixed size is just limiting and as a developer makes editing this more difficult than it needs to be.
I do my development on 2 30" 4K monitors and have tons of screen real-estate. I either have to patiently right mouse character by character through the values or export the .VF and open into visual studio code to see everything .
