This is my use case: I'm trying to improve my Spanish so I've started reading Spanish-language newspapers in the browser on my phone. What I'd like to do is this: when I need a word or phrase translated to English, highlight the text, hit the settings button, and have a translate option show up. Or something comparably simple.
Currently the only options that show up under settings when a word is highlighted are: Share, Find, Web Search
I have Google Translate installed and I realize that I could copy the highlighted text and then paste it into that app, but I'd prefer something that didn't require jumping between apps.
