Unlike a popup, a floating pane is not modal; you can switch to other panes and windows while fzf is running, move and resize the pane with the mouse, zoom it to fullscreen, and use copy-mode in it. - Floating pane always has a native border, so 'border-native' is implied; give new 'border-fzf' option to fall back to a popup where fzf draws its own border - Popup is also used on tmux versions below 3.7, or when the window is too small to fit a floating pane - new-pane does not block until the command finishes and does not propagate the exit status; block on a wait-for channel signaled by the pane and pass the exit status through a temporary file - Watchdog process signals the channel when the pane is closed abnormally (e.g. kill-pane) - Kill the pane when the proxy process is interrupted, like a popup dying with its client - Unzoom the window before creating the floating pane; doing so over a zoomed window crashes the tmux server on 3.7b, and newer versions of tmux unzoom the window anyway - Floating pane size excludes the border and the position is that of the content area; treat the requested size as the total footprint including the border for consistency with popups - Close the pane on exit even when remain-on-exit is on - Pre-create the exit status file with O_EXCL to prevent tampering on a shared TMPDIR
