Time tracking for tasks and projects.
Allow time tracking for tasks. This could be done by adding a start / pause button to tasks. It would also be cool to be able to export this data for use in another tool.
Time tracking is available in parolu, see https://parolu.uservoice.com/knowledgebase/articles/808185-how-can-i-track-time-for-a-todo for a brief overview. You can also export your tracked times for use in third-party apps.
