Sparrow has released version 1.4 of its eponymous email app. This update primarily involves performance and user-interface improvements, with everything from composing to synchronizing receiving a speed boost and some polish. Sparrow 1.4 also adds a few welcome new features, such as integration with the file sharing service CloudApp, pull-to-refresh, and support for proper first-to-last message sorting in conversation view. Several bug fixes round out the update. If Sparrow 1.4 prompts for your password at every launch, Sparrow suggests some possible workarounds until version 1.4.1 appears.

Enabling Auto Spelling Correction in Snow Leopard
In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.
