I wasn't a fan of the icon so created my own, including an associated status item. Concept is a forked arrow to indicate how the request may be redirected to different browsers, with a window to represent the browser.

Happy to share if it's something you/others are interested in, otherwise no worries.

Personal preference I guess, but I love this.

I'm not a big fan of the current icon, as it appears not just on the app but also on every document associated with a browser (eg every .html file).

Very nice logo. I'll think about it!
