TotalFinder

This is a repost from my Twitter and Facebook feeds, but so this hits my homepage I'm including it here! TotalFinder gives you tabbed browsing in the Finder in Mac OS X 10.6 (Snow Leopard). It's only in Alpha stage but to me seems good enough to be a Beta (eg. so far no issues!). Check it out: http://totalfinder.binaryage.com/
