Every day starts the same. Open up iterm2, start up a tmux session and create 3 windows. One for working (generating models, opening up the Rails console, etc), one for the server, and one for running autotest in the background. Then, I name the Tmux session appropriately along with all the windows. It takes about 5-10 minutes to get this all set up nicely in the morning. I got kind of tired doing it and felt like it was wasted time. After some research and some honing, I've created the following script:
Hope you find it useful! For easy reference and forking I've created a gist.
