Let's take a look inside labview.rsc first...
Four of the connector pane patterns actually have names:
4833: "monnie pleaser"
4834: "super monnie pleaser"
4835: "monnie would be pleased-er"
4836: "add supports 2 ddt"
I guess this book wasn't lying. (edit: This is on page 122, and actually, it did get it slightly wrong: the two conpanes shown in the text are actually 4834 and 4835, respectively.)
Two cursors with rather...interesting names:
64: "order sucker"
65: "order squirter"
Someone at NI has a dirty sense of humor 😛
There's some resources that correspond to the style values for VI scripting. Some of them aren't in the style list; unfortunately attempting to use these just gives an error:
2051: "Comment Node" - says "Case" in the data, and gives "Unable to create new object" instead of the usual "object not found" error
2358: "Line of Script"
3902: "Growable Node with Header"
3905: "ExtFuncTerminalTipStrings" - data says "External Function Node", and has names for "path in", "path out", and the standard error in/out terminals
9008: "Select Menu Item" - with all the menu nodes. Looks like at one point they were working on a primitive for programmatically activating menu items.
Someone found some hidden structure types a while back. All but one of them didn't work, and that other one is now an official part of LabVIEW. I found the image for the "Race Structure", which I've posted to that thread:
There's also this super-minimalist "Alternate Splash Screen":
And some monochrome sprite sheets—looks like the old Boolean constant graphics are still there. From what I know about internal VI data structures, I wouldn't be surprised if those were still used if you load a VI created in an old version of LabVIEW.
Just thought I'd share. Curious if anyone has seen these before!
