Been using this for a few days now. Excellent solution!
EDIT: It's been months since I started using Klokd! I've been searching for an extension to boost my productivity for a while. After using it for a while, now it has become a part of my day-to-day life.
Above all, I contacted the developer to request some changes and features I really wanted, to make my work easier. To my surprise, it didn't even take three hours and I had everything I wanted. Highly recommended!
