I have just created a new plugin - Time Tracker
The plugin tracks the amount of time I spend on each project.
I built it to help me with keeping track of how much time I spend on each project I'm working on.
The plugin tracks activity within the editor and if activity is not evident for 5 minutes, pauses.
All time data is stored in a file within the project root named .time which is a CSV file containing the time saved as well as the previous amount of time spent on the project.
Feel free to let me know how it works for you and if you have any suggestions or requests for further updates. I would like to make this as useful as possible.
