Warning icon on missing export

I would love a red warning icon or something to let you know that one of the green export is missing (same as currently done for missing python expressions).

The problem with the way that it is now is at a glance you can’t really tell that the export is missing or there is a problem because the missing export still looks green, and without flying down the parameter so when you have lots of nodes and lots of missing green exports it becomes very tedious and hard to find errors.
