Nested Replies

I've been busy setting up my first login site for our 90+ community groups across the country using Ultimate Member. I bought the ForumWP Plugin as it looks great but am realizing a number of simple things missing. Most recently, nested replies. Am I correct that a user can only reply to the thread. It would seem that they should be able to reply to another reply. Nesting the reply under the reply they are replying too.... right? Is there a setting I'm missing to turn this on? 

If not, is this an upcoming feature? It will be necessary for the groups that I have that will be using this as these forums are a important communication tool and it would be entirely too confusing if each new reply was simply added to the bottom of the thread... 

Thanks!
