Run QML Translation Test - this runs the translation test for the currently open ui.qml file.
Run Project Translation Test - this runs the same translation tests but for several ui.qml files at the same time.
IMO the wording indicates that these are two different kind of test but they are the same, maybe word it something like "Run Translation Test on/for...."
Then we have Import/Export (there are no import functions here) with the sub categories (these are not tool tips but actual UI elements:
- Export used translations to JSON - This exports all translations from the database that are currently used in the open project.
- Export currents documents translations to JSON - This exports all translations in use in the files you currently have open.
