Great, thank you.

Started from a toggle option (e.g. Show Bytecode), python source code lines 
are amended with the disassembly below (unnumbered). 

In debug mode, when catching an exception and bytecode display is enabled, the 
offending opcode should be emphasized in the bytecode disassembly 
(dis.distb()). 

See Python build-in dis module and e.g. https://pymotw.com/3/dis/. 

In a future version, single stepping through the bytecode would be awesome 
(but I'm not sure, if interfaces for such functionality are available 
already).

Cheers,
Pete
