FYI, iTerm2 is still in alpha. From the site:

"BUT iTerm2 IS IN ALPHA! The stability of iTerm2 varies from release to release. Major features that are planned for the first full release haven't been implemented yet, and until that day it will not receive Beta status. That said, many (hundreds to thousands) of people use iTerm2 every day. While some versions are more stable than others, there have been several trouble-free versions released. It's at least worth a try!"
