My timetracker application is now known as Klok. With the new name comes some new features, bug fixes and an updated UI.
The new features include a collapsed view allowing you to tuck it away in the corner where you can see what task you are currently working on and how long you have been working on it.
For bug fixes there were a few minor ones. The most significant caused a problem when you dragged the end time and dropped it before the start time it would cause some weird issues. Now, if you do this it knows enough to swap the times so that the earlier time becomes the start time.
Download it and give it a try. Please feel free to comment on the name, icon, ui, etc.
