Screenshot sharers should shout in celebration, though they shouldn’t try saying that three times fast. Skitch has been bumped to version 1.0.4, and its most notable new feature is that it no longer requires that you create a skitch.com account in order to use the software. Other improvements include a simplified Welcome screen, and a fix for a crash affecting some 10.6.6 users. (Free, 6.5 MB)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
