+## Launch new tmux mode
+
+Previous mode was working only when only one session was running. Since libtmux does not provide a way to identify tmux session the code is running in.
+
+
+This new mode will need a `pane_path` which pattern is `<session_name>:<window_name>:[<pane_id>]`
+
+Regarding `pane_path` :
+- session identified by `session_name` must exist.
+- if windows identified by `window_name`: 
+  - does not exist: it will be created then pane number is ignored if specified
+  - exist and `pane_id`:
+    - is not specified: command will be sent to all panes in the window
+    - does not exist: a new pane will be created (similar to previous mode)
+    - exist: guess what
+
+Note: within tmux session `prefix-q` willdisplay panes number
+
+```
+# will send command to all pane in arsenal-windows (windows creation needed) 
+./run --tmux-new tmux-pentest:arsenal-windows:
+
+# will send command to a new pane
+./run --tmux-new tmux-pentest:arsenal-windows:99
+
+# will send command to pane 3
+./run --tmux-new tmux-pentest:arsenal-windows:3
+```
