The new gui looks nice.
However it's a real pitty that wit still has the fragmentation bug on the windows platform. So I would not recommend anyone on windows that wants to run games off fat or ntfs to use the wit set of tools and the guis that use it.
I'm sorry for the harsh criticism but I have reported this already about a year ago but tried again today and wit still heavily fragments the created files.
Here is an example of an iso to .wbfs conversion: 194 fragments
(and it gets worse with some 4gb game reaching 800+ fragments)

same conversion using wbfs_file:

Wii Backup Manager also creates the files fine, without fragmenting them.
