Hello!

Today I finally got around to giving wezterm a try and was now playing around with my config.
One thing I really like to have on my terminal emulators is for new windows to always start maximized, so that when I use Super+T (my global keybind to open a new terminal window), it fills my entire screen.

Now, I've read #284 and used both GUI events as follows:

wezterm.on("gui-startup", function(cmd)
	local _, _, window = mux.spawn_window(cmd or {})
	window:gui_window():maximize()
end)

wezterm.on("gui-attached", function(_)
	mux.get_window():gui_window():maximize()
end)

The first one works great, wezterm's first window is maximized (so are windows spawned with --always-new-process), but subsequent ones are not.
I've even chucked some prints in both, and I see that gui-startup is being called, but gui-attached isn't.

Am I missing something obvious (likely!) or is this not working as intended?

I have absolutely no idea how it works but it does:

  local seen = {}
  wezterm.on('window-focus-changed', function(window, pane)
    local wid = window:window_id()
    if not seen[wid] then
      seen[wid] = true
      window:maximize()
    end
  end)

The docs don't state if the GUI window ID is unique. From what I've seen, window IDs are not unique, but they still work.

EDIT: Another approach could be abuse of the window configuration overrides via some unused option:

  wezterm.on('window-focus-changed', function(window, pane)
    local overrides = window:get_config_overrides() or {}
    if not overrides.allow_win32_input_mode then
      window:maximize()
      overrides.allow_win32_input_mode = true
      window:set_config_overrides(overrides)
    end
  end)

I'm on Linux so allow_win32_input_mode is useless here, in theory even the presence of the option in the override could do the trick.
