Today, at first ever Evernote Trunk Conference in downtown San Francisco, Phil Libin, CEO of Evernote, announced that the company has officially acquired Skitch, a screen capture and sketch app for the Mac. The move should help increase distribution for the small app, and Skitch's founders added that they plan on distributing Skitch to both the iOS and Android platforms, too. Evernote also announced that it will be making the app free in the Mac App Store.

Skitch lets you take a screenshot and annotate it, highlight passages, and draw on your photos. Evernote has already been using this technology in its desktop app for some time now, but with the official announcement it now "really has the potential to take off." Libin also announced that the company is working on other acquisitions, going after companies that bring a "transformative feel" to the Evernote experience. "We want Evernote to become the same ubiquitous platform as Facebook and [Zynga's games] have become," adds Libin.

The company also announced a massive update to its iOS app. Dubbing it the "most requested features release", the update will include rich-text editing between desktop and mobile platforms, access to shared notebooks, search capabilities within a note, a security lock for the app itself, and a complete new iPad redesign. The refreshed user-interface displays your notes as individual stacks of pages, rather than lumping them all in on the left-hand side of the screen.

Evernote is also uprooting its desktop app and streamlined it for OS X Lion. The desktop app will have Full Screen mode and share a lot of the same UI elements as the upcoming refreshed iPad app.
