For a large notebook, it is convenient to add sections and wrap codes for easy display. However, I find that when I evaluate a piece of wrapped code by clicking on the vertical bar on the right hand side and press Shift+Enter, if the wrapped code contains error such as false assertion, then, this piece of code is still wrapped, so I cannot see whether there is errors when evaluating the wrapped code.
Hence, is there a way to unwrap and display cells with errors when evaluating wrapped code? Or is there a way to fast locate wrapped cells with errors? Or, at the least, is there a way to know if errors happen when evaluating wrapped code? Thank you.
