If this is easy for you to implement, it would be a great addition.

Sorry for not getting back to you earlier.

I will make sure to add this feature in the next version, it should be easy enough to do.

I agree that this would be an excellent addition, especially as an alternative to the problem described in #11.

I often want to write "two contractions at once"---one contraction above, and another contraction below.
