I'm busy writing Ariane 2 and just used a new feature for the first time (in general use, outside of development). When you click on a #gemini link on Android Ariane will display this preview, it's very lightweight and loads extremely quickly. You can promote to the full browser in the overflow menu or by clicking any links, but if you're just hopping between Tusky or the web and Gemini it's a much smoother experience. If you're familiar with #android it's a similar concept to Chrome Custom Tabs
