Agreed on the config. I just launch a Claude code in my vimrc directory now if I want to change anything about my setup or have any questions about how to do something.
Also, I love running a tmux pane for vim, and then like 4 or 5 more -- a few Claude code instances, one for the dev environment, one for interacting with jj/git or other random commands. So easy to switch between tasks. My main annoyance with my setup is that my Bluetooth trackball times out after a period of inactivity, and when I eventually need to use the pointer again there's a lag while it reconnects...
