Initially, I’m guessing it wouldn’t matter, but over time I can see them adding features like being able to share text via the share menu or long-press context menu, so that would be handy. Maybe far down the line it could even act as a digital assistant, so you could maybe map it to the assistant trigger button and provide voice input and get voice replies. Of course, it’s all just wishful thinking, in all likelyhood it’ll remain a glorified web wrapper.
