Pair assets with briefs, check versions, carry revision notes. Every one is ready to run, and you can adjust it in plain language.
Your creator gets the reviewer's requested changes and current draft together, so they can start the next revision without chasing files.
Your campaign team gets a shortcut to the approved asset in its launch folder, with no handoff to chase.
Your original maker gets the rework task and sees why the reviewer rejected the proof, with the reason tied to the reviewed file.
