A few days ago, just after I released Feed Rango, Ed Wellbrook showed me his take on an improved UI for Feed Wrangler. Although my attempt was just to make the existing Feed Wrangler UI better with minimal code, Ed had gone way further with his design and it looked gorgeous. Ed managed to even change the icons used on the site, which gives it an elegant look.
I helped Ed build his design into working browser extensions for Safari and Chrome, which he has released here.
I did email David Smith before releasing Feed Rango, but never heard back from him.
