The new version supports 10.1.x subtitle font and style settings.
So its the first app on the market which makes use of this new feature in FCPX 10.1.
The app makes it easy to transport the settings inside subtitle source files directly into a FCPX timeline/project using XML.
The user also can select to overwrite the settings of a given XML template.
The app supports SBV, SRT and text STL source files
