I spend way too much time customizing vim/bash/terminal/younameit.
Here's how my MacVim window looks:
I implemented a Powerline like prompt for Bash:
- Displays the current git branch
- Changes color if the last command exited with a failure code
- It's all done in a Python script, so you could go nuts with it
The .bashrc also has a handy function for adding bash aliases for git commands, without losing bash completion:
- Make the vi command open files in a single MacVim window
