The DLX translation provider, contributed by Fahry-a and merged in PR #13.
New: DLX translation provider
Third translation provider alongside Google Translate and Custom AI (BYOK).
DLX-compatible endpoints (formerly DeepLX): no API key required, self-hostable server proxying DeepL.
New provider panel with endpoint URL, translation mode, and Test Connection.
Batch mode by default — the whole lyric sheet goes out as one request per song (DLX preserves newlines); a per-line mode is available as an option.
Language mapping from the extension's selector codes to DLX codes (uppercase ISO-639-1, regional variants, and aliases like Filipino→TL, Norwegian→NB, Kurdish→KMR).
No default endpoint is bundled — the user explicitly chooses the server. See the DLX Provider page for options, including a self-hosting guide.
Locale strings for all 11 locales.

Fixes

Popup setting changes (target language, etc.) now apply immediately — no more toggling the translate button. Root cause: tabs.query({url}) requires a host permission the extension doesn't have, so popup messages never reached the content script. Fixed via chrome.storage.onChanged + tab queries without URL filter + a translate() queue so requests arriving mid-pass are re-run instead of dropped.
Consistent DLX translations on synced lyrics — the observer no longer re-translates lines that Spotify re-renders for dynamic highlighting; cache misses are batched via a 200 ms debounce instead of translating per-line.
DLX batch requests serialized — the observer can't fire per-line requests while a batch is in flight; misses accumulate and flush in one follow-up batch.
DLX batch failures stop cleanly — an error marker is shown on the translate button instead of fanning out per-line requests that could produce inconsistent results.
Custom AI cache namespace — AI results are cached under customAI (not google), and the observer reads ['customAI', 'google'], so re-rendered lines keep the AI translation; the AI render loop no longer reads a raw cache key.
DLX & Custom AI endpoints only apply after host permission granted — settings are saved before the permission prompt (which can close the popup), the prompt is requested before await (user-gesture requirement), and settings propagate only on success; a successful Test Connection also pushes settings to open tabs.


Version 0.0.0.19

• Added Custom AI Translation Provider (compatible with OpenAI/BYOK endpoints) allowing users to use their own AI API key and model.
• Added popup settings for AI: API Endpoint, API Key, Model Name, Thinking Mode toggle, and a "Test Connection" button.
• Added "Instant preview" (AI failover toggle): instantly displays Google Translate results while the AI batch translates in the background.
• Added loading indicator and AI color gradient effect to the translate button on the player controls.
• Added visual error feedback (red "!") on the player's translate button when AI requests fail.
• Optimized network requests and billing: duplicate request prevention, safe re-entrancy guard, and cache anchoring based on unique song titles.
• Moved broad site permissions (https://*/*) to optional host permissions, requesting access dynamically at runtime to protect privacy.
• Added cache management controls in the popup: clear current song cache, clear all cache, and a debug option to clear all extension storage (with confirmation prompt).
• Automatically defaults target language to the browser language on fresh installations.
• Refactored popup UI layout, theme, and spacing for a cleaner look.
