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)
Copy Excel Selection as a Picture
Want to show someone a chunk of an Excel spreadsheet via email or iChat? You could take a screenshot, but if you want to show just a portion of the Excel window and you don't use a utility like Snapz Pro, you can do this right from within Excel 2008. Make a selection, hold down the Shift key, and choose Copy Picture from the Edit menu. You can select whether the selection will be rendered as though it was shown on screen or as though it was printed. Then just switch to your desired destination and paste.
