Taskbar widget (Windows)
On Windows, Ping Monitor can put a live summary of your hosts in the taskbar, so you can keep an eye on them without the main window open at all. It fits itself to whatever space the taskbar can spare.
Wide layout
Given room to work with, the widget lists host names and their current latency, coloured by status – green for good, amber for degraded, red for offline or critical:

Compact layout
When width runs short – a crowded taskbar, or a vertical one – it falls back to a 2×2 block of dots counting how many hosts are in each state:

Turning it on and off
It is on by default. View → Taskbar Widget toggles it, as does the matching item on the tray icon’s right-click menu, and your choice is remembered.
You do not need Ping Monitor in the foreground to benefit from it. Minimise the main window and keep the widget in your taskbar: as you go about your day the host latencies sit quietly in the corner of your eye, all green. The moment one turns amber or red you notice without breaking your flow – and the alerts back it up if you happen to be looking away.
