sagenb hidden

[aishen]

Hi,
In sagenb one can hide list of command to make a result, I can't do that in jupyter notebook is there a way ?
I do geometry examples with sagemath, sure I could use other software but I prefer use sagemath because by hand I can notice lot of interesting construction. Another thing I would like is thickness in gridlines
Regards
Henri
