The browser extension acts as a simple start/stop timer, and adds the recorded time to YouTrack issues as workitems.
YouTrack's inbuilt time tracking does not offer great tools for starting and stopping timers. Other third party time trackers lack integration with YouTrack or do not add the tracked time to the issues.
This extension provides a simple start/stop style timer which has no external dependencies but YouTrack itself. All tracked time is added to issues in the form of work items. No signup is required and no data is sent anywhere, but to your own YouTrack instance.
