+### Process Viewer <VersionBadge version="v0.14.5" />
+
+The Process Viewer shows a live list of running processes on any connected host. It is similar to `top` or `htop`, displaying PID, command, CPU%, and memory usage. On Linux it also shows process status and thread count.
+
+Columns are sortable by clicking their headers. Right-clicking a row lets you send Unix signals (SIGTERM, SIGKILL, etc.) or copy the PID. You can filter the list by pressing <Kbd k="Cmd:f"/> and typing a search term. Press <Kbd k="Space"/> to pause live updates (useful when inspecting a specific process); press it again to resume.
