- Color in the Feature list
- When there is a problem with a feature, you may see orange text in the Feature list and dialog title.

- Dimension highlighting

From there, select Ignore faulty part warning (for...). Note that this option is only available within the original Part Studio of the faulty geometry.
To re-show a faulty geometry warning, select Show faulty part warning (for...) from the context menu at any time.
