The browser Timer for Active Collab project management application.
This extension will install a timer right in your Chrome browser. That means you will be able to have both your Active Collab projects and timer in the same place. It will help you to make any time updates you need and follow your tasks in the same time.
The browser timer layout fits into the Active Collab interface. It enhances all details of the opened task and in the same time it uses low surface. By double-clicking on the timer icon you can display or hide all details. That will save work space and will allow you to browse through different tasks or projects.
