Script Summary: This hides the annoying upgrade checklist TripIt puts at the top of every page when you have a free account.
Version: 0.2
When you don't have a TripIt Pro account, TripIt shows a "Four Steps to Travel Zen" checklist on every page, the last "check" of which is to upgrade to TripIt Pro. There is no way to dismiss this upgrade nag/notification. This script hides it.
