 ### Features
 
-- **The interface can be translated, and Polish has started.** mc-webui was written English-only, with every label and message baked into the code. There is now a translation system behind it, and a **Language** setting at the top of Settings → Appearance. So far it covers the main window — menu, chat, its dialogs and **Settings** — plus every panel that opens in its own window: **System Log**, **Console**, **My Repeaters**, **Path Analyzer**, **Contacts** and **Direct Messages**. Message bubbles now translate too: the button tooltips under a message, the SNR/hops/route line, the route pop-up, and the channel-management dialog. Some of the short messages the app shows while it works are still English; they follow next. Your choice applies to the browser you set it in and also becomes the default for anyone else opening the server without a preference of their own.
+- **The interface can be translated, and Polish has started.** mc-webui was written English-only, with every label and message baked into the code. There is now a translation system behind it, and a **Language** setting at the top of Settings → Appearance. It covers the whole interface: the main window — menu, chat, message bubbles, its dialogs and **Settings** — every panel that opens in its own window (**System Log**, **Console**, **My Repeaters**, **Path Analyzer**, **Contacts**, **Direct Messages**), and the running commentary too: the small toasts after every action, the confirmation dialogs, the search results, the update flow and the notifications your phone shows when the app is in the background. Error text that comes back from the server itself is still English — that is the one part left, and it is a separate job. Your choice applies to the browser you set it in and also becomes the default for anyone else opening the server without a preference of their own.
 - **You can add a language yourself, without waiting for a release.** A language is a single file. Copy `en.json` from `app/translations/`, translate the values, and drop it into a `translations` folder inside your config directory — the same place the database lives. Refresh the page and it appears in the Language list, named however you named it, with no rebuild and no restart. Anything you leave untranslated falls back to English, so a half-finished translation is perfectly usable. A file you drop in also overrides one that ships with the app, so you can correct the built-in Polish on your own server. English and Polish ship in the box; everything else is open to whoever wants to write it. See [translations.md](translations.md), which explains the format and — importantly — which words to leave alone: mesh terms like flood, hop, advert, RSSI and the repeater roles stay English in every language, because that is what the firmware, the CLI and the forums all use. The Console and the log lines themselves stay English for the same reason.
 - **Times and dates behave the same in every language.** Only the words are translated — "Yesterday" becomes "Wczoraj", "5 min ago" becomes "5 min temu". The clock and the number formatting keep following your browser's own settings, so switching the menus to English will not suddenly turn your 24-hour clock into "9:53 AM". One display of large numbers on the repeater statistics page had been hard-coded to American thousands separators; it now follows your locale like everything else.
