Less than two weeks after the release of Mellel 3.2 (12 June 2013), developer RedleX has released Mellel 3.2.1, which fixes compatibility issues with Mac OS X 10.5 Leopard. The word processor update has also restored support for automatic baseline shift adjustments for MathType equations and features smarter application of default languages with new documents.

Set Per-Folder Views in the Finder
Tired of navigating to a particular folder and having to switch to List View every time? With Finder in Leopard, you can set viewing preference for each individual folder. Just navigate to it, and set the view the way you want (Column, List, Icon, or Cover Flow). Then choose View > Show View Options (Command-J) and in the window that appears, select the Always Open In... checkbox.
