The terminal role was badly mapped in Qt on Linux, this should be working with 
Qt 5.12.4, I have a few patches to Konsole for some other unlabeled buttons 
and such.

The terminal widget is presented as editable text, is that the best approach? 
And it has children (some menu and other stuff iirc).

Does that make sense?
