Running with Crayons has released Alfred 2.4, adding support for OS X Yosemite, with new Yosemite Light and Dark built-in themes and the addition of Helvetica Neue and Helvetica Neue Light fonts to the theme editor. The keyboard-driven launcher no longer syncs window position (due to different Macs having different location requirements), but adds a new option for displaying fuzzy match file system navigation results. For those who purchase the feature-enhanced Powerpack, Alfred provides more robust nil checking when searching for snippets when doing placeholder replacements, improves the performance of activating and watching clipboard history, and fixes a failure to move or copy a file when the filename contains a grave accent. (Free, £15 for Powerpack, 3.1 MB, release notes, 10.6+)
Disable Caps Lock
If you find yourself pressing the Caps Lock key accidentally as much as I do, note that you can disable it entirely in Mac OS X. Open the Keyboard & Mouse preference pane, click the Modifier Keys button, and in the dialog that appears, select No Action from the Caps Lock pop-up menu. You could remap it to another modifier instead, but that might make using differently configured Macs more difficult.
