Hello Felix,

The screen output could be extended by an area displaying a preview of the data most recently read.

Sounds like an useful feedback.

If it is not too much effort it could be displayed "hex editor" style and the number of preview-lines could be made configurable? Assuming that there is some kind of input buffer in the current implementation just the last few n*16 bytes from it could be included in the output.

Looks nice. And I think it could be implemented without too much effort.

Most read data:
   16E33A  05 00 50 89 05 00 51 89  05 00 52 89 05 00 53 89 ..P...Q...R...S.

I would prefer another header instead of "Most read data". Preferably one that coincides with the name of the option used to enable the feature (--data-preview).

Suggestions about both, the header and the option, are welcome. The least confusing the better. :-)

But don't expect a release soon. Just now I am on vacation and a few days ago the power supply of my computer died suddenly, which will delay everything (until I rebuild my working setup on another machine). :-(

Best regards,
