[IPython-User] [notebook] switch display of cell numbers

[K.-Michael Aye]

Could we have the possibilty for switching off not only the line 
numbers within cells (as it already exists), but also to remove the 
display of the cell numbers that reflect the execution history on the 
very left?
I think it can be desirable at times, when using the notebook for 
blogging to switch off the numbering.

Possible?

Happy New Year everybody!
