When you start a new translation project (e.g. by opening a file to be translated with the MetaTexis command to open files), either the Start Assistant dialog or the Document Options dialog is shown. The Document Options mode is recommended for experienced users who would like to avoid to go through each step of the Start Assistant.
If the option For new translation show Start Assistant is active, the Start Assistant will be shown. If the option For new translation show Document Options is active, the Document Options will be shown.
