Boards — watch many panes at once

A board is a named, cross-server pane dashboard. Pin any tmux window from any server into a board, and the board renders all pinned panes side-by-side in a horizontally-scrollable layout — perfect for watching three parallel agent sessions, or comparing a just dev server’s output against the agent that’s editing it.

Pinning a window

Four ways to pin a window to a board:

Sidebar pin icon — every window row in the sidebar has a pin icon. Click it to open a popover listing existing boards (click to pin/unpin), plus a “Pin to new board…” input that creates a new board on first pin.
Command palette (Cmd+K) — Board: Pin Current Window, Board: Unpin Current Window, Board: Switch to <name>, Board: Leave Board View.
Board pane header — each pinned pane shows an unpin button in its header for one-click removal.
From the shell / an agent — rk board pin <name> @N pins a window by id (needs rk serve up); rk board show|unpin|reorder cover the rest of the board surface.

Inside a board

Cmd+] / Cmd+[ cycles pane focus to the next / previous pane (wraps).
Click a pane to focus it; keystrokes route to that pane’s terminal.
Drag the pane edge to resize (desktop only; widths persist per-board in localStorage).
On mobile, panes render as a single-pane swipe carousel.

Where pin state lives

Pin state lives in tmux (via the @rk_ses_pin_board session option on the window’s _rk-pin-* pin session) so it follows the window, not the browser — open the same board URL on your phone and you see the same panes. Pane widths are intentionally local to each device.
