Yes, I also heard good things about Weblate. In fact, I am looking forward to FOSDEM'20 where I plan to attend the Webplate presentations and hopefully also talk to its authors. I would be more than happy to use a specialized tool for the translating itself, and let AMOS do the rest what it was designed for - the Automated Manipulation of Strings (i.e. tracking the moodle core string changes, allowing the Plugins directory to register plugin strings etc).
Great! I wish you a successful FOSDEM.
