Lookmark is a great utility by Claes Jacobsson to bookmark apps for later and download them when you can. Today's 2.0 update to Lookmark, which I've been testing over the past few days, adds the ability to bookmark any iTunes content and a solid extension that can add bookmarks directly from Safari.
It's quite impressive: if you try it on a website that mentions apps like MacStories, the extension will scan links on the webpage and you'll get a popup at the bottom to save apps for later.
Also new today: a Price Watch subscription service to be alerted of price changes for bookmarked apps. That's going to come in handy for @MacStoriesDeals.
