 # AX Copilot - 媛쒕컻 臾몄꽌
 
+- Document update: 2026-04-05 00:43 (KST) - Added a shared workspace entry chip to both Cowork and Code bottom bars so workspace switching now appears in the same position across task modes instead of hiding behind only the path label.
+- Document update: 2026-04-05 00:43 (KST) - The workspace search popup now starts with a `current / recent / all` summary strip, making the active workspace and available scope visible before the row list just like the other location-oriented popups.

 - Document update: 2026-04-05 00:34 (KST) - Exposed current service/model daily usage directly in the AX Agent context card, and expanded the hover panel to show current-model usage, current-model post-compaction usage, and top model usage for the day using the new per-model daily token buckets.
 - Document update: 2026-04-05 00:34 (KST) - Added a long-safe token formatting path for large per-model aggregates so context usage summaries keep the same K/M style even when daily model totals exceed the older int-based formatting path.
