We may need a more extensive offline mode at some stage (e.g. by the time we really want to deploy to 3GPP). It’s not simply working offline to create a variant of a document. It could be someone who wants to do meeting preparation in a plane, so they’d need multiple drafts or documents, all the variants/CRs proposed to those documents, maybe if they’re chairman they would want to do an updated agenda based on this information etc.
