The contexts, topics and criteria are saved with the data.
Tip: if you want to create a data file with only these set-ups, for example to use within a team or to pass to a friend, use the Archiving function with an archive date for which you don't have actions done: the created archived file will only contain the contexts, topics and criteria.
The settings of the Review Actions screen (Tabs, columns, filters, etc) can be transported between platforms. They are saved in a separate file called ReviewActions.xml. This file needs to reside in the same folder as your data file.
Tip: if you want different settings for work and personal, save the 2 data files in different folders. When you open the data file, TR opens the ReviewActions.xml file present in the same folder.
The other settings under Options/Miscellaneous are saved on each platform.
