I tried to translate with Translation tool, but it is too cumbersome. Translation would need some kind of categorising, so user can translate parts of the functionality. Like Stock module.
Expressions are also used in several parts of the app, and if it ok for some module, maybe it is not ok for some other module.
So I switched to translating cvs file.
Also some expressions are not listed in file and tool for finding missing translations does not work properly.
