This translation tool has a very basic user interface. With the strings displayed on top along the the full string in the reference language and it's translation below. As indicated in the tools menu, the F3 key will perform a Google translate of the string into the selected language. The magic to this tool is in the File -> Import menu where we can import and export resources files from projects or into other formats including the industry standard TMX format.
It's also possible to filter the strings to a subset of the resources. In this dialog box, we can select a specific project or form and have the tool only display the strings that are on that form. The tool makes the assumption that a given string translate the same no matter the location in the application. This may not be strictly true on professional projects, but it makes life pretty easy for most general projects.
