+# Connection & Tab Visibility
+
+## The omnibox popup problem
+
+When Chrome opens fresh, the only CDP `type: "page"` targets are `chrome://inspect` and `chrome://omnibox-popup.top-chrome/` (a 1px invisible viewport). If the daemon attaches to the omnibox popup, all subsequent work — including `new_tab()` and `goto_url()` — happens on tabs that exist in CDP but may not be visible in the Chrome UI.
+
+The daemon's `attach_first_page()` handles this by creating an `about:blank` tab when no real pages exist. If you still end up on an invisible tab, use `switch_tab()` which calls `Target.activateTarget` to bring the tab to front.
+
+## Startup sequence
+
+1. Check if a daemon is already running with `daemon_alive()`
+2. If stale sockets exist but daemon is dead, clean them up
+3. List open tabs with `list_tabs()` to see what's available
+4. `ensure_real_tab()` attaches to a real page
+5. `switch_tab(target_id)` both attaches AND activates (brings to front)
+
+```python
+if not daemon_alive():
+    import os, ipc
+    ipc.cleanup_endpoint("default")
+    pid = ipc.pid_path("default")
+    if pid.exists(): pid.unlink()
+    ensure_daemon()
+
+tabs = list_tabs()
+for t in tabs:
+    print(t["url"][:60])
+
+tab = ensure_real_tab()
+```
+
+## Bringing Chrome to front
+
+If Chrome is behind other windows or on another desktop:
+
+```python
+import subprocess
+subprocess.run(["osascript", "-e", 'tell application "Google Chrome" to activate'])
+```
+
+## Navigating
+
+Prefer navigating an existing tab over `new_tab()`. Tabs created via CDP's `Target.createTarget` are visible but may open behind the active tab.
+
+```python
+tab = ensure_real_tab()
+goto_url("https://example.com")
+```
