It is an old blog post, but I saw on this page the following road map for Box and Files Connect:

Any word on #2 and #3?

1. The ability to support both file browsing and searching in both Salesforce Classic and Lightning Experience 

2. The ability to preview file references directly in Salesforce! (Very Cool!) 

3. The ability to create new documents in Box directly From Salesforce (Um...Even Cooler!!)
