Uncomplex has tweaked Mailplane, its WebKit wrapper for Gmail, with a handful of minor fixes and improvements. Picture optimization in outgoing messages can now be controlled via AppleScript, dragged messages now disappear as expected, dragging images onto Mailplane's icon now optimizes pictures reliably, and keyboard shortcut functionality broken by Gmail changes has been restored ($24.95 new, free update, 19.9 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.
