netssh multi opens one pane per host in a tmux window or zellij tab. Hosts come from names, tag:TAG (NetBox and static hosts), cluster:NAME (NetBox virtualization clusters; devices by default, --kind vm|all), and groups from the config (@name, nested, with cycle detection). Every pane runs netssh HOST, so lookup, rules, and jump hosts apply. - tmux: a new window inside tmux, else a new session that is attached; tiled layout, pane borders with the host and a [SYNC] marker. - zellij: a generated grid layout; a new tab inside zellij, else a new session. - --sync broadcasts typing to all panes; netssh sync toggles it in the current tmux window or zellij tab. - TUI: Space marks hosts, Ctrl+A marks all, Enter opens them together. - Configurator: multiplexer, panes per window, groups. NetBox SearchAll gains a cluster filter (name to cluster IDs per instance), and cache entries keep the host's cluster for completion and an offline fallback. Panes skip the 24-hour background refresh (checked once by multi) and get HOME/XDG paths but no NETSSH_* values, which would expose tokens in the process list. testenv/tests/15-multi.sh checks real tmux and zellij sessions, including a broadcast command arriving on all three cluster nodes.
