Sparrow, the minimal email client for the Mac that recently gained with full Lion compatibility, received a new update in the Mac App Store, this time adding native integration with file sharing service CloudApp, a "pull to refresh" gesture to check for new messages, and a number of fixes and improvements aimed at enhancing the email experience and make it faster and more stable.
With CloudApp support, users are now able to drag & drop files into Sparrow's compose window, and have the app automatically upload them to CloudApp and insert a clickable link in the message. Once authenticated with your CloudApp account in Sparrow's preferences, every time you'd like to send an attachment through CloudApp, you won't need to have CloudApp installed on your Mac: Sparrow will directly communicate with CloudApp's servers and upload the file for you. The UI for this action is very simple -- the top section of the message is a CloudApp "drop zone", while the lower part at the bottom is for classic email attachments as explained by the developers in this article. There is a new cloud indicator in the top toolbar of the compose window to show the status of an upload, which will turn blue after it's complete. Overall, CloudApp integration is well done, simple and useful if you share with CloudApp on a daily basis.
Sparrow 1.4 also comes with the "pull to refresh" gesture made popular by Loren Brichter's Tweetie on the iPhone years ago, and later implemented by thousands of other App Store apps. In Sparrow, you can pull the inbox to check for new messages, and whilst I don't think I'll ever use this functionality as I like my email client to stay in the background and refresh every few minutes automatically, I assume some people who want to manually check for new messages will like this option.
As usual with every Sparrow update, there's a series of bug fixes and improvements under the hood. Sparrow now syncs and sends emails faster than before, and Gmail-like reverse threads have been implemented in the conversation view. Sparrow is now compatible with Zoho and Lotus Domino, it's got a new draft management system and the mail database has been improved, too.
Sparrow 1.4 can be considered a minor update, but it'll make those who rely on CloudApp for their file sharing needs more efficient when dealing with email. You can get Sparrow 1.4 on the Mac App Store.
