WebUI Translation Editor

Choose the WebUI i18n folder (interface/src/i18n in the EMS-ESP32 repository). Every <language>/index.ts file in it is read and shown side by side. Nothing is uploaded; the files are read and written entirely in your browser. You can download the i18n folder from  https://github.com/emsesp/EMS-ESP32/tree/dev/interface/src/i18n and place it in your WebUI folder.

Your browser can't write to a folder directly (use Chrome, Edge or another Chromium-based browser for that). Save will download a zip with the changed files instead.
