Hello @Claudio Acosta Creating a language module isn't hard at all—I have 13 of them. I also struggled with how to handle it as quickly as possible, etc., and believe me, editing a language module is much faster, more organized, and you can be sure your translations will always stay in place, whereas if your database crashes, you'll lose everything. When you uninstall the module, the database gets cleaned up and no unwanted clutter remains; if you do it manually, you have to do everything manually again.

As for scaring you, I didn’t mean to, but I’ve had it happen where a mistake I made while manually entering keys threw my entire website off.

Which path you choose is, of course, up to you, and if this works for you, there’s no problem with it as long as you’re careful and make regular backups.

As for the frontend-backend language separation, you can handle it the way I have it shown in the screenshot.
