When sharing a document with people (through email link at least) I can make them an Editor or a Viewer. If they are an Editor they can Edit and Suggest. I'd like to give access only to Suggest, and leave me the owner as the only one who can accept the suggestions or make edits. This would make a lot of sense to me.
I would like to be able to make someone a Viewer or an Editor or a Suggester. Three separate roles that I can assign to their name/email.
