Add “on/off switch” for line numbers

Hi Jeff,

Can you please give us a on/off switch for line numbers?

Right now, we have to:

1. Sselect the prismatic block
2. Expand “Advanced”
3. Fill in “line-numbers”

As you can see, it takes many clicks. We have posts with sometimes 10 blocks with line numbers.

A on/off button under the Prismatic sidebar menu would be great.

See example:

Thanks.
