Describe the bug
tmux -CC support seems to not react to tmux induced layout change

Configuration
no config
Expected Behavior
We should immediately see the new pane appear.

Use wezterm command to do that, the purpose is tmux -CC is to use local command/render to wrap /replace tmux native command/render.
This is a surprising answer, it seems to me that the appeal of tmux -CC is that the details of which terminal emulator you actually use (iterm2/wezterm) are abstracted away, I would not expect needing to know if I actually am running in wezterm/iterm2/classical tmux to programatically create a new pane.

Click the ‘+’ on the tab of wezterm then you have a tmux new window, is that harder than you type “ tmux new-window”?

@joexue you missed the 'programmatically' part, aka create a pane from a script for example

Right If you use script, for now, you can create all windows you need then attach them. Or somehow use wezterm command (if we have) or Lua script or wezterm shortcut key to do that.
is there no signal from tmux that a split was created? We should respond to and reflect the current state for those sorts of scripted changes too!

yes, there is, probably easy to add this into wezterm.
I’ll have a look if this really matters.
