I have noticed in some places in the LabVIEW IDE that the selected attribute is not properly highlighted. A perfect example is Cursor Attributes on a Waveform Graph:
The currently selected Point Style and Cursor Style Attributes are highlighted with a blue box, but the Line Style and Line Width are not highlighted with the current values. This is important to know, because it is difficult to tell the difference in line widths, and could even be impossible if the cursor is off the screen.
I can only find these two places right now that the current selection is not highlighted, but once I find more I'll post in the comments.
