I think its a good idea to have a workrave unity launcher which displays timers information on little progress bars, just like nautilus, tranmission and others do.

The latest (yet unreleased) version supports Unity. Through workrave offers an indicator instead of a launcher.

Thanks for creating a Unity indicator for Workrave. 

I think the indicator is more useful/discrete than a launcher. In fact I have a launcher on my system that displays a grey square with a cog inside, and I wish I could remove it and rely purely on the indicator. 

Clicking the launcher reveals the little window with the three timers inside. I think it would would be if that window could be launched from the indicator. I have played around with preferences but haven't yet been able to remove the launcher.

In the current version you can right click on the indicator and select 'open' to open the main window. If the main window is closed, it will disappear from the launchers.
