Wow! Tomi has some wonderful suggestions. I just wanted to chime in and second everything that was said there. There are even graphical examples!
The configurable node thing just jumped up and bit me last week while I was trying to parse text from a file. The default behavior of the Read File primitive is now "Convert EOL" so it takes the \r\n and makes it just \n. I had the Read function in a few places and I have to visit each instance and uncheck the Convert EOL option. That was annoying. It was double annoying because I had no way to know which instances I had already changed without looking at the pop-up menu.
Perhaps a tool-tip or something could show the abbreviated configuration of one or those nodes. I still like the idea of quick configuraiton dialogs. The operative word is "quick". Those Properties dialogs for controls and configuration pages for Express VIs are rather slow.
