I just tried this app, and got 2 very different and very wrong fonts.

I did actually love the functionality of the extension, however I just observed some rather aggressive user tracking (screenshot: https://jumpshare.com/v/xLZ5fMJFWZOJD5Fu7plR ) Why does Chengyin Liu need to know and log when we open new tabs and which websites we go to? I think there's a reasonable threshold for understanding how your extensions might be used, but to me this seems a bit sketchy. Hopefully nothing nefarious happening, but until there's an opt out and/or a clear and upfront indication that the extension tracks your data (and perhaps an explanation around why it does so) i'm removing from chrome :(
