This nice one logic analizer could operate as an In-circuit digital IC tester?
This current design would need a custom definiable truth table (picture attached) loader feature (with an internal or external editor, ...industrial standard file types?)
plus a visible compare/search feature on the screen. Where bad data found that piece can be marked by a different (inverted?) color.
It could be a great feature beacause all other kind of logic tests and quick compare could be done by this extension.
