If you could change anything about Forum Spark, what would you change?

I have noticed that Forum Spark is becoming very popular in the forum world, and I will admit, from what I have seen, it does look like an amazing forum option for those who wish to start out a new forum, which I am currently looking into.

I have seen so much about what people enjoy about Forum Spark, but nothing so far about anything anyone would change if they could.

What would you change on Forum Spark if you could?
