Smart Translation Toggle: The page translation shortcut now acts as a two-way toggle, allowing you to easily switch back and forth between the translated version and the original text. The default shortcut has also moved to Alt+A (⌥A on macOS) to prevent system conflicts and ensure reliable binding.

Streamlined Settings: All preference changes and API key edits are now saved automatically in the background within a third of a second. Additionally, the translation engines are now grouped into Recommended, Translation Services, and AI Translators for much easier navigation.

Carbon Color Palette: The interface has shifted to a neutral-gray theme that removes any yellow undertones. Text contrast has been slightly softened to provide a more comfortable and less tiring reading experience during long sessions.

Enhanced PDF Support on Firefox: Full PDF translation is now supported on Firefox for both online links and local file:// documents. The extension now intercepts these documents early to open them seamlessly within the native cleartext viewer.

Unified Custom AI Engine: The custom engine setup is now consolidated into a single profile that automatically detects OpenAI and Anthropic protocols. It smartly identifies and routes individual models on mixed gateways, while updating your settings status dynamically.

Polished Interface Details: The custom model selector now leads with a searchable dropdown menu to reduce clutter and make model selection effortless. Minor visual bugs, such as height mismatches and background page-bouncing on macOS, have also been fixed.
