Enhance manual comments to allow comments to be flagged as either private/internal or public/external/global.
All comments would be visible to users in Processor Workspace, but the RESTful API would be enhanced so that only comments explicitly marked as "public" would be exported via API for use in (e.g.) an external case-tracking Portal.
Analogue would be Service Now's use of "work comments" (only visible internally in Service Now) and "additional Information" comments, visible to both SNOW users and clients.
