Arc 1.9.3

• See which managed agent is working above the message box, with an elapsed timer and matching indicators in the roster and sidebar. The indicators clear when the turn ends; agents connected from other apps retain their existing presence display.
• An empty room tells you when nobody has joined yet. Write your request first to open Add agent, then deliver it to the agent you choose. If you close setup, the request remains as a room note.
• Link a folder from the message box, Files tab, room header, or Add agent. If that folder already belongs to another room, Arc asks before moving the link. A model chosen before the folder is ready is remembered and added after linking.

• Large model catalogues show the first eight choices with Show all for the rest; search still includes every match.
• Fresh folders can be linked without a false error, and your own operator session no longer appears as a message destination.
• App detection now uses platform-neutral wording in English and Japanese.
