Download Witgui 2.0.4 (Mac OS X Snow Leopard or newer)
Fixed bugs
Creating a parent directory when converting/renaming a file works now.
New features
Formatting a drive as WBFS is now supported.
Updates
This is the first version of Witgui that works on Snow Leopard, Lion and Mountain Lion. Accessing WBFS partitions on Lion is now supported (all unmounted partitions get listed as a potential WBFS partition; trying to open a listed non-WBFS partition will simply cause an error).
The details popover is automatically updated when the selected game changes inside the same window.
