The just-released Mailplane 2.1.6 from Uncomplex adds built-in support for the highly interesting Rapportive plug-in (see "Rapportive Plug-in Replaces Gmail Ads with Sender Info," 27 March 2010). Mailplane 2.1.6 also now works with the Share > Send via Mail menu items in the iWork '09 applications. With them, you can email your document via Mailplane in its native format or as a Word, Excel, PowerPoint, or PDF document. A few minor bugs have also been fixed, some of which were related to Gmail changes. ($24.95 new, free update, 6.7 MB)
Open Links from Mail in the Background
Tired of switching back and forth between Mail and your Web browser every time you click a link in a TidBITS issue or other email message? Here's an easy workaround. Hold down the Command key when you click links in Mail to open them in your browser without switching away from Mail. That way you can keep reading in Mail and then read all the Web pages you've opened.
