             "The mouse-wheel Zoom/Scroll setting works on real mice now. Accelerated wheels (Magic Mouse, Logitech smooth scrolling) report fractional scroll amounts that were being mistaken for a trackpad, so the wheel always panned no matter what the setting said.",
             "A browser helper that talks itself into refusing (\"I\u2019m a text-based AI\") no longer poisons its browser for every later task. Refused and fabricated runs are forgotten instead of remembered, and agents can ask for a completely fresh browser when one misbehaves.",
             "Agents no longer claim \"the user told me to stop\" when it was OpenSwarm\u2019s own housekeeping talking. Internal wrap-up and retry messages now identify themselves, so an agent\u2019s explanation of why it stopped reflects what actually happened.",
+            "Double-clicking empty canvas reliably fits every card on screen again, and an app an agent builds or drives now docks as a small card beside the chat instead of covering it. When a website needs you to sign in, the agent now pauses, tells you, and continues by itself once you log in on its browser card.",
             "Agents no longer lose their tools partway through a run. Under heavy multi-agent load, a safety timer could mistake a queued browser or app task for a lost one and restart the agent's tool connection mid-task; it now checks the right task before acting.",
             "Heavy sessions no longer vanish without a trace. When memory climbs past the safe line the app now sheds weight itself: preview thumbnails pause and refetchable caches drop, instead of growing until the operating system kills it mid-task.",
