Some of my favorite Sublime Text 2 options. Just click Preferences menu > Settings - User to open settings.

Preferences.sublime-settings

{
	// Save files when focus changes, 
	// like to a new file or another program
	"save_on_focus_lost": true,

	// Make tabs small
	"tab_size": 2,

	// Keep tabs.  Tabs are used to indent the start of lines
	// and different devs like different indention levels.
	// Spaces should be used to indent anywhere else.
	// <let the flame wars begin>
	"translate_tabs_to_spaces": false,

	// Don't wrap long lines of text by default
	"word_wrap": false,

	// Just a null value to keep commas on previous lines
	"": ""
