Describe the enhancement you're suggesting.

When editing HEX dump in-app you cannot see the last bit (out of screen on the right corner).
Implement way to copy/paste whole block.
Suggest to implement "import dump from file" with following formats .mct/.json/.bin/.mdf/.dump/.eml .
Implement way to edit in-app (add or view) user keys (mf_classic_dict_user.nfc).

Anything else?

Trying to work on it.
