One pain point of the Labview UI for me is eliminating the recessed border of controls - clusters and arrays in particular since there is no "system" version of these controls. You have to activate the paintbrush tool, click on a 2-pixel wide line, then do the spacebar-and-transparent color dance. It's something I do regularly, it's clumsy, and it's not at all intuitive for a new user.
But if you have a subpanel control and you go into the Visible Items section of the popup menu, you can toggle the frame as a visible item:
This should be on EVERYTHING!!!!
