The most common question asked when training users on 2.0 is whether there is a way to accept or reject all suggestions within a story, ala some track changes programs. When we tell them there isn't, their next question is whether there is a way to hide/show all suggestions in a story as an alternative. Users are looking for a faster way to clean up the file, in essence. Their preference would be for the first suggestion, but they could live with the second method.
Hi Martha! Thanks for submitting this idea. We don't have immediate plans for accept or reject all but understand the value add here in cleaning up stories. We'll keep this in mind as we make improvements to Composer!
