Have just added this and seems to work really well.
One issue I've had it with the width setting - I would like the poll width to automatically fit the container size so it also works across mobile devices etc (setting a fixed width seems not to work with this).
I have tried leaving the width column empty and that seems to work but I cannot save it as an option. Presumably if I set it to 0 it won't work.
How should I proceed to set a width that automatically fits the container?
