Being able to create projects, but for windows and panes

Is your feature request related to a problem? Please describe. Tmuxinator is excellent at creating custom projects, which are incredible at producing almost all forms of pane arrangements and windows. I like it, but this is sometimes frustrating when all you want is merely a new window with x panes and x layout. Or even splitting the current window to x panes with x layout

Describe the solution you'd like I would like to have a command to create a custom window with its panes and layout and commands, and also splitting the current window in ...

Describe alternatives you've considered All I can do to fix this issue is to literally create a shell script with

tmux new-window
tmux split-pane -h
tmux split-pane -v
tmux select-pane -t 1

As an example. Additional context I would like it to be I the same format as the session project. I’d recommend creating a separate folder inside tmuxinator directory where such can be stored.

It must be a separate command other than the project command. This is to be able to create projects and (whatever you choose to name it) and be able to use the same names for both commands. As for the resizing current window command it may take a different folder inside tmuxinator directory.
