When editing drafts of print and digital materials, using comments/annotations in Box has been my team's go-to. However, I think the level of collaboration for that option could use improvement. It would be nice to be able to respond to directly under someone's comment so everyone knows what is being referred to, and I don't have to type "in response to {name's} note on {thing}..." to get my point across. It would also be nice to resolve/remove comments in some cases.
