• tmux-style window selector:
  Ctrl+B, w now opens a full-screen window chooser like tmux's
  choose-tree. The list shows each window's number, name, pane count, and
  tmux-style flags (* current, - last), with a live preview of the
  selected window's panes below the list. Windows expand into a tree:
  Right/l shows a window's panes as child rows (-/+ marks
  expanded/collapsed), Left/h folds them again. Selecting a pane row
  previews just that pane, Enter on it switches to the window and focuses
  that pane, and x kills it. On window rows, move with the arrow keys or
  j/k, jump with 1-9, switch with Enter, and kill with x (both
  kills ask y/N for confirmation); close the chooser with Esc or q.
  The mouse works too: scroll to move the selection, click a row to switch
  to it, or click outside the popup to close it; moving the mouse does not
  dismiss the chooser.
