Some git aliases and a tmux binding
Add ruby snippets file
Remove git autocorrect

I was getting more false positives than I like since I use many short
aliases. Also, git was already informing me when it guessed I had a
typo which was sufficient for my needs.
Use choose-tree over choose-session in tmux

Choose tree gives a list of sessions that can each be expanded to show
the windows, allowing me to target the specific window within a session
if I choose to.
Automatically resize vim buffers when vim resizes

This is useful for rebalancing buffers after splitting a tmux pane off
to the side.
Add vim titlecase and underline helpers for prose
Add mapping to convert to 1.8 style hash syntax
Run CtrlP relative current directory
Maximize fugitive commit window
Switch to commentary from nerdcommenter

I like things that take motions, and commentary is a commenting plugin
that does just that
Simplify NerdTree mappings
Update envup script to return 1 on failure
