Feature-Request: Show ASCII-Debug-Messages while decoding custom frame

[Schmarrele]

It would be nice if the tool would allow to show filtered readable debug messages, simulataneously to the plotted data.
Basically readable ascii-data, which is not part of the custom-frame.

My use-case looks like the following:
I am transmitting 1000 packages/second with a custom frame (HEADER + LEN + DATA + CRC), but maybe 1 debug-package/second. (Like "DEBUG: Hello world!")
Just by reading the raw-data, it is quite hard to find the actual debug-message in there.
Therefore it would already be a big help if a pure text window is available (supporting new-line characters),
which just shows all (ASCII) symbols which coudn't bee decoded by the custom frame.
