So I am unclear what creates/enables the green borders in panel layouts. In addition to the box, it looks like footprints with the green also gain opaque properties which makes them easier to see over the rail behind them.  So in the example below, CR429, SCR328 and 331 all have the border. SR348 and 325 don't. SCR351 did have it, until I updated the symbol and then it went away.  Anybody able to explain what drives this so I can make sure my footprints are fitting the requirements and getting the box?  Thanks.
