Hi there! We've got some great new features for you in this update. • Buy Me a Coffee tip jar: A new optional tip jar is now available in Settings. If you'd like to support development, you can offer a small, medium, or big coffee — it's completely voluntary and unlocks nothing. The app remains fully free and open source. • Search tools discovery: Settings → Web Search now includes a "Load Available Tools" button that fetches the list of search providers configured in your LiteLLM server, so you no longer need to type the tool name manually. The first available tool is auto-selected if your saved name is no longer valid. • Privacy screen (iOS): A new toggle in Settings → Privacy lets you hide app content when switching apps or opening the App Switcher, replacing it with a blurred overlay — just like banking apps. • Reasoning streaming in agent mode: Model thinking tokens (reasoning/thinking content) are now streamed in real time during agent mode, so you can follow along as the model reasons through its response. • Minor bug fixes and improvements for a smoother experience, including better resilience when streaming responses finish with empty content. Thanks for your continued support and for helping us build the best possible LLM client together. Remember: you can suggest and vote on new features from the Feedback section in settings.
