The overall experience is very positive.

I started to use Desklog as a cheaper alternative to our previous time tracking app.
It was not only cheaper but provided cost/revenue analysis and a nicer user interface.
The support response was also great.

Desklog misses automatic project change based on criteria like browsed web url/title.
I would also welcome a small widget, which would indicate, what project/task is currently tracked.

As I heard new interface and features are in the pipeline so it should get even better soon. So it is no-brainer, you should have it.
