Many Tricks has released version 3.1 of Witch (http://manytricks.com/witch), its window switching utility for Mac OS X. The new version adds a couple of new features, improves on many behaviors, and fixes a few bugs.
In version 3.1, the Witch panel appears after a very short delay, so it can be used (as with Command-Tab) to toggle between two open windows without seeing the Witch panel flash onscreen. A major memory leak has been identified and plugged. Witch no longer uses increasing amounts of RAM over time, and uses less RAM overall than version 3.0.
Updated help files explain all of Witch 3’s features. Version 3.1 handles Parallels’ windows more gracefully when Parallels is running in Coherence or Crystal view modes. Hidden windows are now shown with a translucent icon, so they can be easily identified at a glance.
Witch 3.1 is a free update for all Witch 3 users. Witch 3 is US$19 for new users and $8 for users of Witch 2.x.
