Thanks! Your Hive-Engine witness is @cadengine, right? As @rishi556 suggested, I implemented the same feature you got on vote.hive.uno to add a "by" line on witness alt-accounts, so if you want you can add your main account on "witness_owner" (inside "posting_json_metadata") so the site can display that info too. 🙂
Also, I think you are using a low-res image on @cadengine as it is not displaying correctly on the site (your main account displays the image just fine).
Indeed it is. Those are some good suggestions and I'll do them before I properly announce it (if that day ever comes).
