ProfessorProfessorLMConfig does not send changes. It can alert that "something changed", which is about as useful as a red light in your car console saying "something is wrong".
As far as the rest -- the issue is there is currently no viable way to solve this without bolting on an API method entirely outside of LM. I can do this, but I hate being forced to do it all the time. There are some simple fixes, like allow tables to display properties and allow setting properties without cutting and pasting 50+ lines of API code repeatedly (glad you are on that one!), that would make things much better. I have had numerous conversations with product development folks and improvements happen all the time. Unfortunately, most of those are the glitzy marketable types, and the lower level nuts and bolts tend to get less attention.
